I tried installing postgresql in my server which has centos
I followed this link
I am facing few complexity here.
I could not locate postgresql file in /etc directory.
psql (8.4.13, server 9.2.4) WARNING: psql version 8.4, server version 9.2. Some psql features might not work.
How can i solve these issues. can anyone suggest me.
I could not locate postgresql file in /etc directory.
The tutorial you linked to suggests the config files are in /var/lib/pgsql/9.2/data/...
psql (8.4.13, server 9.2.4) WARNING: psql version 8.4, server version 9.2. Some psql features might not work.
You've still got the 8.4 version of psql installed. Use your package tools (rpm/yum) to see what versions of the psql client packages are installed and where the binaries are.
It's common enough to run two different versions of PG on the same machine. Obviously each needs its own data directory and port number. Also, as you've seen psql will check the version number and warn if they are different. Basic queries still work, but obviously an 8.4 version won't know about extensions introduced in 9.1 and that sort of thing.

I'm building a pipeline on Azure DevOps with a Linux image as a base (ubuntu-latest). Here I'm installing PostgreSQL version 12 with PostGIS.
Here's what I install:
sudo apt-get install -y postgresql-12 postgresql-client-12 postgresql-12-postgis-3 postgresql-12-postgis-3-scripts
First I tried to install it without mentioning any version numbers, but then I got the error mentioned below and I followed recommendations to specifically do it like this.
Hence the specifically mentioned version numbers
No special additions, just a plain installation of Postgres.
Installation is going fine without any errors.
Then when I create my database and connect to it, I do CREATE EXTENSION POSTGIS; and I get this error:
psql:./create_tables.sql:3: ERROR: could not open extension control file "/usr/share/postgresql/14/extension/postgis.control": No such file or directory
I'm pulling my hair for some time now about this and I totally don't get where it gets that reference to a version 14 folder from. There is absolutely no version 14 installed.
I also tried to pull the Debian packages from the Postgres.org instead of the Ubuntu libraries, I tried to install PostGIS 2.5 and PostGIS 2.5 scripts packages. But whatever I do, I get the same result. Once I start the pipeline, the image gets built and Postgresql and PostGIS installed and then I get the same error as a result.
Did anyone have this same experience? Where could this library folder reference for version 14 come from?
EDIT 2022/05/21: I've added some checks to the scripts and when checking the version of PostgreSQL(via SELECT version(); ) it gives version 14 (!), which at least explains the error. Apparently version 14 indeed IS installed and runs on the default port 5432. Version 12 that is explicitly installed also runs, it runs on port 5433 (checked via cat /etc/postgresql/12/main/postgresql.conf ). I now explicitly start version 12 and connect in my scripts to port 5433, so I can continue, but I still wonder where that version 14 installation comes from.
Postgres 14 is pre-installed on the Microsoft Hosted agent for ubuntu-20

I have a production machine running debian strecth that I do not want to mess up. I have an app that requires postgres 11 and I'm not sure about a thing. Does the installation from the official postgres debian repo install as an extra server or does it replace the existing 9.6 verssion on debian?
I have tried to dump from version 11 and restore in 9.6 but it throws an error on creation of a sequence:
psql:fas-schema.sql:125: ERROR: syntax error at or near "AS"
LINE 2: AS integer
Just need to be sure 100%
If you want to run multiple versions of PostgreSQL one the same host, you should use official packages provided by PGDG. All the currently supported versions are available.
Though, these packages are not including tools provided by the Debian project, such as pg_ctlcluster or pg_lsclusters.
We have the following requirements. Could anyone suggest which PostgreSQL package to choose?
Server supporting multiple connections on the same port
Trigger
GUI to interact with the server
Features to support back up & restore database
Ability to connect to a remote postgreSQL server
We would require it for both Windows 7 & OS X El Capitan
UPDATE:
The below link contains multiple links to download PostgreSQL. As we can not download all of them & try out, require someone's help to point us to the right package with the above mentioned components/features
postgres
postgres
pgAdmin
pg_dump, pg_restore, psql
psql lets you specify database (including remote) to connect to
All above works both windows and osX
EnterpriseDb has free packages for postgres that include commonly used components like pgAdmin (a GUI). They have packages for both Windows and OS X but I would use homebrew instead for OS X. Homebrew is an OS X package manager. There's several tutorials for installing postgres via Homebrew. Here is one.
You would install pgAdmin separately.
Installing via Homebrew is a little more complex but gives you more flexibility and capability.
If you're just starting out with postgres, the EnterpriseDB packages will be easier.
I installed postgresql 9.3.5 on OS X 10.9.4. I also used psql postgres to create database etc.
Ran in some issues where postgresql no longer works. The error is:
could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/tmp/.s.PGSQL.5432"?
So I brew uninstall postgres. Tried reinstalling but keep getting same error. I looked in the /Library.... and deleted the postgresql folder. Is there a way to fully remove this thing? I'm tempted to reinstall this mac but this is not the way to learn the long way of resolving this issue.
Completely uninstall PostgreSQL 9.0.4 from Mac OSX Lion?
This should work if you had previously used brew to install postgres:
brew uninstall
Double check /usr/local/var/postgres is also gone.
If installed with EnterpriseDB, use the second answer. You might also try it as it seems to be a complete manual uninstall.
Edit: after further review, it seems this is more of an issue with Postgres on OSX where as it defaults to the local installation rather than your installation: PostgreSQL error 'Could not connect to server: No such file or directory'
When trying to get local data to Heroku, I am encountering a version mismatch between two different versions of pg_dump.
Specifically, I am getting this message:
pg_dump: server version: 9.2.2; pg_dump version: 9.1.4
pg_dump: aborting because of server version mismatch
I have found others with this problem, but do not know enough to implement the proposed solutions. (I am new to Ruby on Rails, PostgreSQL, Heroku, and the Mac! Very much at the stage of playing around the picking things up as I go.)
I was thinking I might simplify my life if I uninstalled all PostgreSQL on my local machine and started again with a clean install of PostgreSQL 9.2.2 from http://postgresapp.com/, but I don't know how to go about doing the uninstall.
I'm running Mac OS X Mountain Lion 10.8.2.
OS X 10.8 comes with pg_dump version 9.1.4 in the /usr/bin directory, along with psql and other programs that are client-side PostgreSQL tools. It does not mean that PostgreSQL as a server is installed (unless you have OS X Server Edition).
So you don't have to uninstall PostgreSQL because it's not installed and it's better not to remove these postgres client tools in /usr/bin because they belong to the system as shipped by Apple. They just need to be side-stepped.
The package provided by postgres.app comprises both the PostgreSQL server and the client-side tools of the same version as this server. These tools get installed in /Applications/Postgres.app/Contents/MacOS/bin
To use these instead of the 9.1 ones from Apple when you work in a Terminal, postgres.app documentation says to do:
PATH="/Applications/Postgres.app/Contents/MacOS/bin:$PATH"
and put it in your .profile file.
Once you have done that and you run pg_dump, you should no longer get the error that's it's the wrong version, because it would be the one that ships with postgres.app (currently 9.2.2).
I have this setup and it works OK for me.
If you only need to upgrade your pg_dump to the latest version and you have homebrew and mac, if the app has the latest version and your local pg doesn't:
brew upgrade postgresql
If you're using postgresapp 9.3.x, the path is different. The following worked for me (courtesy of http://sigmyers.com/blog/2013/3/12/postgres-pgdump-version-mismatch-error-postgresapp-postgresappcom)
export PG_BIN_PATH="/Applications/Postgres.app/Contents/Versions/9.3/bin/"
PATH=$PG_BIN_PATH:$PATH
Check here for the latest path: http://postgresapp.com/documentation/cli-tools.html
I'm running Mountain Lion Server. My PostgeSQL server is at version 9.2.1 and the default tools are at 9.1.5.
I had to use:
PATH="/Applications/Server.app/Contents/ServerRoot/usr/bin:$PATH"
to make it work.
Yep, sometimes if you run Postgres.app this may happen after upgrade. Make sure you restart your Postgres.app - it will update your PATH.
In my case I have postgresql installed via homebrew and the executables are here: /usr/local/opt/postgresql#9.6/bin
Or you copy the dump and restore executions to the /Applications/Postgres.app/Contents/SharedSupport folder
or in PdAgmin you point the PG bin Path (in properties -> binary Path) to the path of the executables of your postgre
