I use tableplus for my general admin.
Currently using the docker postgres image at 10.3 for both production and localhost development.
Because tableplus upgraded their postgres 10 drivers to 10.5, I can no longer use pg_restore to restore the backup files which are dumped using 10.5 --format=custom
See image for how I backup using tableplus. And how it uses 10.5 driver
The error message I get is pg_restore: [archiver] unsupported version (1.14) in file header
What i tried
I tried in localhost to simply change the tag for postgres in my dockerfile from 10.3 to 10.5 and it didn't work
original dockerfile
FROM postgres:10.3
COPY ./maintenance /usr/local/bin/maintenance
RUN chmod +x /usr/local/bin/maintenance/*
RUN mv /usr/local/bin/maintenance/* /usr/local/bin \
&& rmdir /usr/local/bin/maintenance
to
FROM postgres:10.5
COPY ./maintenance /usr/local/bin/maintenance
RUN chmod +x /usr/local/bin/maintenance/*
RUN mv /usr/local/bin/maintenance/* /usr/local/bin \
&& rmdir /usr/local/bin/maintenance
My host system for development is macOS.
I have many existing databases and schemas in my development docker postgres. So I am currently stumped as to how to upgrade safely without destroying old data.
Can advise?
Also I think a long term is to figure out how to have data files outside the docker (i.e. inside my host system) so that everytime I want to upgrade my docker image for postgres I can do so safely without fear.
I like to ask about how to switch to such a setup as well.
If I understand you correctly, you want to restore a custom format dump taken with 10.5 into a 10.3 database.
That won't be possible if the archive format has changed between 10.3 and 10.5.
As a workaround, you could use a “plain format” dump (option --format=plain) which does not have an “archive version”. But any problems during restore are yours to deal with, since downgrading PostgreSQL isn't supported.
You should always use the same version for development and production, and you should always use the latest minor release (currently 10.13). Everything else is asking for trouble.
backup as plain text like this: warning! the file will be huge. Around 17x more than regular custom format. My typical 90mb is now 1.75Gb
copy the backup file into the postgres container docker cp ~/path/to/dump/in-host-system/2020-07-08-1.dump <name_of_postgres_container>:/backups
go to the bash of your postgres container docker exec -it <name_of_postgres_container> bash
inside the bash of postgres container: psql -U username -d dbname < backups/2020-07-08-1.dump
That will work
I have installed PostgreSQL in Ubuntu Linux system for OpenProject project management tool.
I searched internet i installed pgadmin tool and i tried to backup.
I could backup, but it backups only the sql query in a file.
I want to backup the whole db example- myproject with all data in it.
I did the following:
Step1/ I set automatic for bash script on ubuntu (use "openproject" user)
#!/bin/bash
Date=`date +"%Y_%m_%d_%H%M"`
openproject run backup
mkdir /var/db/openproject/backup/op_$Date
mv /var/db/openproject/backup/*.gz /var/db/openproject/backup/*.pgdump /var/db/openproject/backup/op_$Date
Step2/ Use "FreeFileSync" to backup from ubuntu server -> dropbox/local host/....
Hoping userful for you!
I had planned an upgrade of artifactory from 6.7.5 to 6.8.1. As part of the upgrade I checked jfrog's repo on github and it looks like they have a new recommended nginx and postgres version.
The current docker-compose is using postgres 9.5 and the new default version if 9.6. Simply pulling down postgres 9.6 however does not do an inplace upgrade.
FATAL: database files are incompatible with server DETAIL: The data
directory was initialized by PostgreSQL version 9.5, which is not
compatible with this version 9.6.11.
The upgrade instructions do not mention anything about how to do the upgrade.
The examples provided in github (https://github.com/jfrog/artifactory-docker-examples) are just examples.
Using them in production could cause issues and backwards compatibility is not guaranteed.
To get over the PostgreSQL matter when upgrading, I would suggest:
$ docker-compose -f yml-file-name.yml stop
edit the yml-file-name.yml and change the docker.bintray.io/postgres:9.6.11 to docker.bintray.io/postgres:9.5.2
$ docker-compose -f yml-file-name.yml up -d
Artifactory should be upgraded after following this, however it will keep using the previous version of the PostgreSQL DB
I have been able to upgrade database using following approach:
Dump all database to an SQL script using old database image; store it in a volume for future import:
# Override PostgreSQL image used to export using old binaries
printf "version: '2.1'\nservices:\n postgresql:\n image: docker.bintray.io/postgres:9.5.2\n" > image_override.yml
started_container=$(docker-compose -f artifactory-pro.yml -f image_override.yml run -d -v sql_dump_volume:/tmp/dump --no-deps postgresql)
# Dump database to a text file in a volume (to make it available for import)
docker exec "${started_container}" bash -c "until pg_isready -q; do sleep 1; done"
docker exec "${started_container}" bash -c "pg_dumpall --clean --if-exists --username=\${POSTGRES_USER} > /tmp/dump/dump.sql"
docker stop "${started_container}"
docker rm --force "${started_container}"
Back up old database directory and prepare a new one:
mv -fv /data/postgresql /data/postgresql.old
mkdir -p /data/postgresql
chown --reference=/data/postgresql.old /data/postgresql
chmod --reference=/data/postgresql.old /data/postgresql
Run a new database image with mounting dump script from step 1. It processes SQL scripts upon startup when setting up a new database, provided it's started as postgres something. We just don't need to leave the server running afterwards, so I provided --version to make entrypoint execute, import the data and quit:
docker-compose -f artifactory-pro.yml run --rm --no-deps -e POSTGRES_DB=postgres -e POSTGRES_USER=root -v sql_dump_volume:/docker-entrypoint-initdb.d postgresql postgres --version
After all this is done, I was able to start Artifactory normally with docker-compose -f artifactory-pro.yml up -d and it started up normally, applying rest of schema and file upgrade procedure as usual.
I have also prepared a script that basically does the above steps along with some additional checks and cleanup. Feel free to use if you find it useful.
So,
My admin installed (don't know how) postgresql 9.2 (64 bit version) on a centos7 machine. The thing is I need to initalize the database so I should run something like:
service postgresql-9.2 initdb
but I get error:
The service command supports only basic LSB actions (start, stop, restart, try-restart, reload, force-reload, status). For other actions, please try to use systemctl.
Did some search and people said that you should initialize via direct call to some script, but every given location does not exists in this CentOS 7 machine.
Like for example this location (yeah, it is for 9.3 and I use 9.2, but similar location does not exist anyway):
/usr/lib/pgsql-9.3/bin/postgresql93-setup initdb
or this
/usr/pgsql-9.3/bin/postgresql93-setup initdb
I found out
/usr/lib64/pgsql
but this directory has only a bunch of '*.so' files.
How the hell do I run initdb for postgresql 9.2 on centos7?
You can run it directly from postgres account
#su - postgres -c pg_ctl initdb
Just installed the Postgresql 9.3 on Centos.
#cd /etc/init.d
#ls postgres*
and there is a posgresql-9.3 script
#./postgresql-9.3
gives you the options to run with and one of them is initdb

I'm using the PostgreSQL database for my Ruby on Rails application (on Mac OS X 10.9).
Are there any detailed instructions on how to upgrade PostgreSQL database?
I'm afraid I will destroy the data in the database or mess it up.
Assuming you've used home-brew to install and upgrade Postgres, you can perform the following steps.
Stop current Postgres server:
launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
Initialize a new 10.1 database:
initdb /usr/local/var/postgres10.1 -E utf8
run pg_upgrade (note: change bin version if you're upgrading from something other than below):
pg_upgrade -v \
-d /usr/local/var/postgres \
-D /usr/local/var/postgres10.1 \
-b /usr/local/Cellar/postgresql/9.6.5/bin/ \
-B /usr/local/Cellar/postgresql/10.1/bin/
-v to enable verbose internal logging
-d the old database cluster configuration directory
-D the new database cluster configuration directory
-b the old PostgreSQL executable directory
-B the new PostgreSQL executable directory
Move new data into place:
cd /usr/local/var
mv postgres postgres9.6
mv postgres10.1 postgres
Restart Postgres:
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
Check /usr/local/var/postgres/server.log for details and to make sure the new server started properly.
Finally, re-install the rails pg gem
gem uninstall pg
gem install pg
I suggest you take some time to read the PostgreSQL documentation to understand exactly what you're doing in the above steps to minimize frustrations.
Despite all answers above, here goes my 5 cents.
It works on any OS and from any-to-any postgres version.
Stop any running postgres instance;
Install the new version and start it; Check if you can connect to the new version as well;
Change old version's postgresql.conf -> port from 5432 to 5433;
Start the old version postgres instance;
Open a terminal and cd to the new version bin folder;
Run pg_dumpall -p 5433 -U <username> | psql -p 5432 -U <username>
Stop old postgres running instance;
Here is the solution for Ubuntu users
First we have to stop postgresql
sudo /etc/init.d/postgresql stop
Create a new file called /etc/apt/sources.list.d/pgdg.list and add below line
deb http://apt.postgresql.org/pub/repos/apt/ utopic-pgdg main
Follow below commands
wget -q -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
sudo apt-get update
sudo apt-get install postgresql-9.4
sudo pg_dropcluster --stop 9.4 main
sudo /etc/init.d/postgresql start
Now we have everything, just need to upgrade it as below
sudo pg_upgradecluster 9.3 main
sudo pg_dropcluster 9.3 main
That's it. Mostly upgraded cluster will run on port number 5433. Check it with below command
sudo pg_lsclusters
If you are using homebrew and homebrew services, you can probably just do:
brew services stop postgresql
brew upgrade postgresql
brew postgresql-upgrade-database
brew services start postgresql
I think this might not work completely if you are using advanced postgres features, but it worked perfectly for me.
Update: This process is the same for upgrading 9.5 through at least 11.5; simply modify the commands to reflect versions 9.6 and 10, where 9.6 is the old version and 10 is the new version. Be sure to adjust the "old" and "new" directories accordingly, too.
I just upgraded PostgreSQL 9.5 to 9.6 on Ubuntu and thought I'd share my findings, as there are a couple of OS/package-specific nuances of which to be aware.
(I didn't want to have to dump and restore data manually, so several of the other answers here were not viable.)
In short, the process consists of installing the new version of PostgreSQL alongside the old version (e.g., 9.5 and 9.6), and then running the pg_upgrade binary, which is explained in (some) detail at https://www.postgresql.org/docs/9.6/static/pgupgrade.html .
The only "tricky" aspect of pg_upgrade is that failure to pass the correct value for an argument, or failure to be logged-in as the correct user or cd to the correct location before executing a command, may lead to cryptic error messages.
On Ubuntu (and probably Debian), provided you are using the "official" repo, deb http://apt.postgresql.org/pub/repos/apt/ xenial-pgdg main, and provided you haven't changed the default filesystem paths or runtime options, the following procedure should do the job.
Install the new version (note that we specify the 9.6, explicitly):
sudo apt install postgresql-9.6
Once installation succeeds, both versions will be running side-by-side, but on different ports. The installation output mentions this, at the bottom, but it's easy to overlook:
Creating new cluster 9.6/main ...
config /etc/postgresql/9.6/main
data /var/lib/postgresql/9.6/main
locale en_US.UTF-8
socket /var/run/postgresql
port 5433
Stop both server instances (this will stop both at the same time):
sudo systemctl stop postgresql
Switch to the dedicated PostgreSQL system user:
su postgres
Move into his home directory (failure to do this will cause errors):
cd ~
pg_upgrade requires the following inputs (pg_upgrade --help tells us this):
When you run pg_upgrade, you must provide the following information:
the data directory for the old cluster (-d DATADIR)
the data directory for the new cluster (-D DATADIR)
the "bin" directory for the old version (-b BINDIR)
the "bin" directory for the new version (-B BINDIR)
These inputs may be specified with "long names", to make them easier to visualize:
-b, --old-bindir=BINDIR old cluster executable directory
-B, --new-bindir=BINDIR new cluster executable directory
-d, --old-datadir=DATADIR old cluster data directory
-D, --new-datadir=DATADIR new cluster data directory
We must also pass the --new-options switch, because failure to do so results in the following:
connection to database failed: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/lib/postgresql/.s.PGSQL.50432"?
This occurs because the default configuration options are applied in the absence of this switch, which results in incorrect connection options being used, hence the socket error.
Execute the pg_upgrade command from the new PostgreSQL version:
/usr/lib/postgresql/9.6/bin/pg_upgrade --old-bindir=/usr/lib/postgresql/9.5/bin --new-bindir=/usr/lib/postgresql/9.6/bin --old-datadir=/var/lib/postgresql/9.5/main --new-datadir=/var/lib/postgresql/9.6/main --old-options=-cconfig_file=/etc/postgresql/9.5/main/postgresql.conf --new-options=-cconfig_file=/etc/postgresql/9.6/main/postgresql.conf
Logout of the dedicated system user account:
exit
The upgrade is now complete, but, the new instance will bind to port 5433 (the standard default is 5432), so keep this in mind if attempting to test the new instance before "cutting-over" to it.
Start the server as normal (again, this will start both the old and new instances):
systemctl start postgresql
If you want to make the new version the default, you will need to edit the effective configuration file, e.g., /etc/postgresql/9.6/main/postgresql.conf, and ensure that the port is defined as such:
port = 5432
If you do this, either change the old version's port number to 5433 at the same time (before starting the services), or, simply remove the old version (this will not remove your actual database content; you would need to use apt --purge remove postgresql-9.5 for that to happen):
apt remove postgresql-9.5
The above command will stop all instances, so you'll need to start the new instance one last time with:
systemctl start postgresql
As a final point of note, don't forget to consider pg_upgrade's good advice:
Upgrade Complete
----------------
Optimizer statistics are not transferred by pg_upgrade so,
once you start the new server, consider running:
./analyze_new_cluster.sh
Running this script will delete the old cluster's data files:
./delete_old_cluster.sh
The user manual covers this topic in depth. You can:
pg_upgrade in-place; or
pg_dump and pg_restore.
If in doubt, do it with dumps. Don't delete the old data directory, just keep it in case something goes wrong / you make a mistake; that way you can just go back to your unchanged 9.3 install.
For details, see the manual.
If you're stuck, post a detailed question explaining how you're stuck, where, and what you tried first. It depends a bit on how you installed PostgreSQL too, as there are several different "distributions" of PostgreSQL for OS X (unfortunately). So you'd need to provide that info.
Standing on the shoulders of the other poor creatures trodding through this muck, I was able to follow these steps to get back up and running after an upgrade to Yosemite:
Assuming you've used home-brew to install and upgrade Postgres, you can perform the following steps.
Stop current Postgres server:
launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
Initialize a new 9.4 database:
initdb /usr/local/var/postgres9.4 -E utf8
Install postgres 9.3 (as it was no longer present on my machine):
brew install homebrew/versions/postgresql93
Add directories removed during Yosemite upgrade:
mkdir -p /usr/local/var/postgres/{pg_tblspc,pg_twophase,pg_stat_tmp}/touch /usr/local/var/postgres/{pg_tblspc,pg_twophase,pg_stat_tmp}/.keep
run pg_upgrade:
pg_upgrade -v -d /usr/local/var/postgres -D /usr/local/var/postgres9.4 -b /usr/local/Cellar/postgresql93/9.3.5/bin/ -B /usr/local/Cellar/postgresql/9.4.0/bin/
Move new data into place:
cd /usr/local/var
mv postgres postgres9.3
mv postgres9.4 postgres
Restart Postgres:
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
Check /usr/local/var/postgres/server.log for details and to make sure the new server started properly.
Finally, re-install related libraries?
pip install --upgrade psycopg2
gem uninstall pg
gem install pg
Looks like the solution has been baked into Homebrew now:
$ brew info postgresql
...
==> Caveats
To migrate existing data from a previous major version of PostgreSQL run:
brew postgresql-upgrade-database
....
On Windows I kept facing different errors messages when trying to use pg_upgrade.
Saved a lot of time for me to just:
Backup DB
Uninstall all copies of PostgreSQL
Install 9.5
Restore DB
This did it for me.
https://gist.github.com/dideler/60c9ce184198666e5ab4
Short and to the point. I honestly don't aim to understand the guts of PostgreSQL, I want to get stuff done.
My solution for upgrading from Postgresql 11 to Postgresql 12 on Windows 10 is the following.
As a first remark you will need to be able stop and start the Postgresql service. You can do this by the following commands in Powershell.
Start:
pg_ctl start -D “d:\postgresql\11\data”
Stop:
pg_ctl stop -D “d:\postgresql\11\data”
Status:
pg_ctl status -D “d:\postgresql\11\data”
It would be wise to make a backup before doing the upgrade. The Postgresql 11 instance must be running. Then to copy the globals do
pg_dumpall -U postgres -g -f d:\bakup\postgresql\11\globals.sql
and then for each database
pg_dump -U postgres -Fc <database> > d:\backup\postgresql\11\<database>.fc
or
pg_dump -U postgres -Fc -d <database> -f d:\backup\postgresql\11\<database>.fc
If not already done install Postgresql 12 (as Postgresql 11 is also installed this will be on port 5433)
Then to do the upgrade as follows:
1) Stop Postgresql 11 service (see above)
2) Edit the postgresql.conf file in d:\postgresql\12\data and change port = 5433 to port = 5432
3) Edit the windows user environment path (windows start then type env) to point to Postgresql 12 instead of Postresql 11
4) Run upgrade by entering the following command.
pg_upgrade `
-b “c:\program files\postgresql\11\bin” `
-B “c:\program files\postgresql\12\bin” `
-d “d:\postgresql\11\data” `
-D “d:\postgresql\12\data” --username=postgres
(In powershell use backtick (or backquote) ` to continue the command on the next line)
5) and finally start the new Postgresql 12 service
pg_ctl start -D “d:\postgresql\12\data”
My solution was to do a combination of these two resources:
https://gist.github.com/tamoyal/2ea1fcdf99c819b4e07d
and
http://www.gab.lc/articles/migration_postgresql_9-3_to_9-4
The second one helped more then the first one. Also to not, don't follow the steps as is as some are not necessary.
Also, if you are not being able to backup the data via postgres console, you can use alternative approach, and backup it with pgAdmin 3 or some other program, like I did in my case.
Also, the link: https://help.ubuntu.com/stable/serverguide/postgresql.html
Helped to set the encrypted password and set md5 for authenticating the postgres user.
After all is done, to check the postgres server version run in terminal:
sudo -u postgres psql postgres
After entering the password run in postgres terminal:
SHOW SERVER_VERSION;
It will output something like:
server_version
----------------
9.4.5
For setting and starting postgres I have used command:
> sudo bash # root
> su postgres # postgres
> /etc/init.d/postgresql start
> /etc/init.d/postgresql stop
And then for restoring database from a file:
> psql -f /home/ubuntu_username/Backup_93.sql postgres
Or if doesn't work try with this one:
> pg_restore --verbose --clean --no-acl --no-owner -h localhost -U postgres -d name_of_database ~/your_file.dump
And if you are using Rails do a bundle exec rake db:migrate after pulling the code :)
For Mac via homebrew:
brew tap petere/postgresql,
brew install <formula> (eg: brew install petere/postgresql/postgresql-9.6)
Remove old Postgres:
brew unlink postgresql
brew link -f postgresql-9.6
If any error happen, don't forget to read and follow brew instruction in each step.

On Windows 10 since I had npm, I installed rimraf package. npm install rimraf -g
Backup all your databases one by one using command pg_dump -U $username --format=c --file=$mydatabase.sqlc $dbname
Then Installed Latest PostgreSQL Version i.e. 11.2 which prompted me to use port 5433 this time.
Followed by Uninstall of older versions of PostgreSQL mine was 10. Note the uninstaller may give a warning of not deleting folder C:\PostgreSQL\10\data. That's why we have the next step using rimraf to permanently delete the folder and it's sub-folders.
change into PostgreSQL install directory and ran the command rimraf 10. 10 is a directory name. Note use your older version of PostgreSQL i.e. 9.5 or something.
Now add C:\PostgreSQL\pg11\bin, C:\PostgreSQL\pg11\lib into the Windows environmental variables. Note my new installed version is 11 thus why I am using pg11.
Navigate to C:\PostgreSQL\data\pg11 then open postgresql.conf edit port = 5433 to port = 5432
That's it. Open cmd and type psql -U postgres
You can now restore all your backed databases one by one using the command pg_restore -U $username --dbname=$databasename $filename
I think this is best link for your solution to update postgres to 9.6
