Unable to install pgagent with application stack builder - postgresql

I'm trying to install pgagent in a windows environment. Postgresql version 9.6 is installed and application stack builder was installed with it. I have followed the steps, detailed here.
The first step in this guide is to create the extension in the maintenance db, and I am not able to do that.
"ERROR: could not open extension control file "C:/Program Files/PostgreSQL/9.6/share/extension/pgagent.control": No such file or directory
SQL state: 58P01"
Tryied to skip this step and go straight to the installation with application stack builder, but the pgAgent tool does not show up.
I also tried to install it as a service using the command line instead of stack builder.
pgAent.exe INSTALL pgAgent -u postgres -p secret hostaddr=127.0.0.1 dbname=postgres user=postgres
This worked to some degree. The only error I get is this.
"Windows could not start pgAgent service on the local computer. Error 1069: The service did not start due to a logon failure."
But I have tried all possible combinations of usernames, passwords, secrets, ports and so on....
Any help would be much appreciated.


I had the same problem. I was able to get pgagent working by downloading and executing the stand-alone installation file pgagent-3.4.0-4-windows.exe from here: http://sbp.enterprisedb.com/getfile.jsp?fileid=11842


I wound up installing the Stack Builder Plus from EDB. Unfortunately, you have to create an account, but it has a lot more options for which pgAgent version you want. Note: You can use Stack Builder for only pulling a pgAgent installation executable and run that on your target servers.


this worked for me :
first I accessed the postgres bin file using cmd: C:\Program Files\PostgreSQL\11\bin
then i tapped this :
pgAgent INSTALL pgAgent -u windowsUser-p windowspassword hostaddr=127.0.0.1 dbaname=postgres user=postgres password=***


Have you choosen a localy installed database before this step ?
You will need to have installed PostgresSql, CLI Commands and Stackbuilder to have the option of installing pgAgent via those eDB installers.

Citus 10.2 not starting an instance of PostgreSQL

I'm using RHEL 8.4 and I followed the installation instruction at Set up a single-node Citus cluster on your own Linux machine from RPM packages..
Step 1 and 2 (Install PostgreSQL 14 and the Citus extension and Initialize the Cluster) went through without any issues.
But When I tried (Step 3: Start the database server)
pg_ctl -D citus -o "-p 9700" -l citus_logfile start
I got the following error in terminal
waiting for server to start.... stopped waiting
pg_ctl: could not start server
Examine the log output.
The log output
FATAL: could not access file "citus": No such file or directory
LOG: database system is shut down
I do have a directory 'citus' in postgres user's home directory with all required files in it along with postgresql.conf
Kindly help.

It appears you ran into one of 2 issues:
Possible issue #1:
You did not successfully install citus package and the citus.so file is missing.
Can you see the file /usr/pgsql-14/lib/citus.so that should be installed via the package citus102_14?
If that is not the case, you should figure out why the package is not installed.
Possible issue #2
You do not run pg_ctl command in the home directory of postgres user.

I was getting the same error. I am using the Postgres compiled from the source file. Thus, instead of
sudo apt-get -y install postgresql-14-citus-10.2
I compiled the source of the Citus from Github and specified the path to location of my Postgres while configuring as:
git clone https://github.com/citusdata/citus.git
cd citus
./configure --prefix=/usr/local/pgsql/
make
sudo make install
I do not get an error during pg_ctl start and I can load extension as CREATE EXTENSION citus;.

How can I install pgAgent for PostgreSQL 9.5 on Windows?

Everything I see about pgAgent says that it can be installed using the StackBuilder wizard that runs after installing PostgreSQL. But the StackBuilder wizards I have do not include pgAgent. How can I get pgAgent?
A screenshot of my StackBuilder dialog box showing the lack of pgAgent can be found here: https://imgur.com/PTopsAA

I think it can't be possible, 9.5 is dead (EOL). but the binaries still can be downloaded from EDB ( https://www.enterprisedb.com/downloads/postgres-postgresql-downloads )
NOTE: pgAgent is available in Debian/Ubuntu (DEB) and Redhat/Fedora
(RPM) packages for Linux users, as well as source code
In the official doc says how: https://www.pgadmin.org/docs/pgadmin4/latest/pgagent_install.html#service-installation-on-windows
Service installation on Windows
pgAgent can install itself as a service on Windows systems. The command line options available are similar to those on Unix systems, but include an additional parameter to tell the service what to do:
Usage:
pgAgent REMOVE <serviceName>
pgAgent INSTALL <serviceName> [options] <connect-string>
pgAgent DEBUG [options] <connect-string>
options:
-u <user or DOMAIN\user>
-p <password>
-d <displayname>
-t <poll time interval in seconds (default 10)>
-r <retry period after connection abort in seconds (>=10, default 30)>
-l <logging verbosity (ERROR=0, WARNING=1, DEBUG=2, default 0)>
The service may be quite simply installed from the command line as follows (adjust the path as required):
"C:\Program Files\pgAgent\bin\pgAgent" INSTALL pgAgent -u postgres -p secret hostaddr=127.0.0.1 dbname=postgres user=postgres
You can then start the service at the command line using net start pgAgent, or from the Services control panel applet. Any logging output or errors will be reported in the Application event log. The DEBUG mode may be used to run pgAgent from a command prompt. When run this way, log messages will output to the command window.

Cannot install cstore_fdw on docker postgres container

Trying to install cstore_fdw on a docker postgres container just to test the columnar functionality, and I'm stuck at the point of build/make the cstore repo.
The os is debian 9, postgres 11, i've installed make and a few tools I need.
The step where you build and run the make cmd, is failing bcz of postgres. Found in "building" section here: https://github.com/citusdata/cstore_fdw
Directories
cstore dir: /var/lib/postgresql/cstore_fdw/
pg config dir: /var/lib/postgresql/data/postgresql.conf
at the cstore dir I run the following and get the following error, and I don't know why.
PATH=/var/lib/postgresql/data/:$PATH make
Makefile:38: /usr/lib/postgresql/11/lib/pgxs/src/makefiles/pgxs.mk: No such file or directory
Makefile:45: *** PostgreSQL 9.3 or 9.4 or 9.5 or 9.6 or 10 or 11 is required to compile this extension. Stop.
I've also tried to use the pg bin directory in the make cmd, which is /usr/lib/postgresql/11/bin/, I think, and that gives same error.
Thanks for any help

Your docker image does not contain the PostgreSQL extension building infrastructure PGXS.
You will need to install that and the PostgreSQL header files.

Tables could not be fetched - Error loading schema content

I open workbench and connect to a local database on XAMPP and when open the connection the schema show the error message:
"tables could not be fetched"

run this command on terminal
mysql_upgrade -u root -p

Run this command on terminal
sudo /opt/lampp/bin/mysql_upgrade
And as per the comment by #jonathan-delean , you might need to run this instead:
sudo /opt/lampp/bin/mysql_upgrade -u root -p

For XAMPP, this worked for me - run this on terminal:
sudo /Applications/XAMPP/xamppfiles/bin/mysql_upgrade
Disconnect then reconnect to your db.

First, locate the directory of which Xampp is installed at.
In linux you can just type this in a terminal:
whereis xampp
In my case (btw I use arch, jk) it was located at /opt/lampp/bin . If you're using windows, you may find it under a different location, like in C:\Program Files\xampp\bin
Next, locate the file mysql_upgrade and execute it as an administrator or a sudo.
If you're using Linux:
cd /opt/lampp/bin then sudo ./mysql_upgrade
According to MySQL documentation:
Each time you upgrade MySQL, you should execute mysql_upgrade, which
looks for incompatibilities with the upgraded MySQL server: It
upgrades the system tables in the mysql schema so that you can take
advantage of new privileges or capabilities that might have been
added. It upgrades the Performance Schema, INFORMATION_SCHEMA, and sys
schema. It examines user schemas.
So I believe mysql_upgrade should resolve the problem. It worked for me before.
More on mysql_upgrade here:
4.4.5 mysql_upgrade — Check and Upgrade MySQL Tables

That's because the latest XAMPP use MariaDB and MYSQL Workbench is using MYSQL Database, so they are not fully compatible, raising that error for example.You can try to downgrade to some of the previous XAMPP versions.

For MacOS users:
sudo /Applications/XAMPP/bin/mysql_upgrade

I created another Connection in MySQL workbench, and the fetching problem for me was resloved.

I did have this problem today, the reason is:
Error Code: 1356 View 'test.xyz' references invalid table(s) or column(s) or function(s) or definer/invoker of view lack rights to use them
After dropping those view (actually those views) the error was solved.
currently working with MySQL Workbench 8.0.28, and MySQL 8.0.28.

for macOS users run this on terminal:
sudo /Applications/XAMPP/bin/mysql_upgrade
this worked for me

See YouTube video: MySQL 8 - The message "Tables Could Not Be Fetched"
https://www.youtube.com/watch?v=phi6o8B7kKI
Either a table or view or function used in code has been dropped; hence the "...could not be fetched".

this works for me
sudo mysql_upgrade --force

As #Brittany Layne Rapheal says, with that command you can fix the issue, is also recommended to give execution privileges to that file:
So you should run first this command:
sudo chmod +x /Applications/XAMPP/xamppfiles/bin/mysql_upgrade
And then, this:
sudo /Applications/XAMPP/xamppfiles/bin/mysql_upgrade --force
--force is necessary because as the parameter says to force the update (Necessary)

After installing postgres 9.4 on fedora 20, couldn't launch psql

I have installed postgres 9.4 on fedora 20.
i have followed the steps through the link below
https://wiki.postgresql.org/wiki/YUM_Installation
I have started the server using the command
service postgresql-9.4 initdb
Then I set the auto start using the command
chkconfig postgresql-9.4 on
I am able to connect with Data base server via pg admin
but I am not able to connect with postgres DB server or SQL command line via terminal
If I enter psql for postgres/or any user, it says command not found.
can any one please help me on this.

You need to go to the installation bin directory and use './ExecutableFile' to run when logged in with postgres user.
So, use ./psql when you are in bin directory.
Or you can use "export PATH=path/to/bin/" to avoid using './'
