You tried a lot to do this and ... what happened? Exact error messages? What precisely didn't work when you tried? Also: PostgreSQL version? – Craig Ringer
Thanks, Craig for comment, I am using postgre sql 9.2. I am getting error that install command is not recognize with windows command prompt. I also try with postgre sql command prompt. please help in this.... thanks. – Anvesh
Well, it's a Windows command prompt command, entering it in psql will do you no good. Edit your question and add the exact error you get. Add a screenshot showing it if that's easier. Then comment here so notifications are sent. – Craig Ringer

PgAgent is probably not installed

The pgAgent download page says:

pgAgent is a job scheduler for PostgreSQL which may be managed using pgAdmin. Prior to pgAdmin v1.9, pgAgent shipped as part of pgAdmin. From pgAdmin v1.9 onwards, pgAgent is shipped as a separate application.

And then it provides a download link to http://www.postgresql.org/ftp/pgadmin3/release/pgagent/
But the problem is there's only source code there. There are also SQL files in the tarball but they're useless without pgagent.exe.

How to install it

Apparently the correct way to install a pre-compiled pgAgent is with the Stack Builder installer that also happens to be the primary installation method on Windows for the PostgreSQL server itself. That's what is suggested on the official download page: http://www.postgresql.org/download/windows/

If you have already installed PostgreSQL for Windows with this method, the installer is available under the name Application Stack Builder in the PostgreSQL 9.2 folder in Windows Start Menu.

StackBuilder will normally recognize your installed PostgreSQL version(s), and suggest to install among various programs pgAgent in the Add-ons, tools and utilities category. Once you check pgAgent and continue with the installation, it will download it and launch its setup. The setup phase includes runnning the necessary SQL statements and installing the PostgreSQL scheduling Agent - pgAgent windows service. If this step is successful, there is nothing else to do, the functionality will be available in pgAdmin for creating jobs.

What's misleading in the docs

The latest pgAdmin docs at http://www.pgadmin.org/docs/1.16/pgagent-install.html has a Service installation on Windows chapter that says:

The service may be quite simply installed from the command line as follows (adjusting the path as required):

"C:\Program Files\pgAdmin III\pgAgent" INSTALL pgAgent -u postgres -p secret hostaddr=127.0.0.1 dbname=postgres user=postgres

However in the majority of cases this is not going to be of help because either:

  • pgAgent install is done by pgAgent setup as launched by StackBuilder and this step is not necessary.
  • or you have got pgAdmin alone and pgagent.exe will not be installed so this step is not possible.

pgAdmin will be successfully installed after downloading the compressed file from

https://www.pgadmin.org/download/pgagent-source-code/

there inside, you will find the file "sql\pgagent.sql"

Toss the content of this file into the Query Tool and run it. That will install pgAgent. Refresh your database connection to see the result. The tab pgAgent Jobs should have been created at the root level for your connection.

There is no need of using the INSTALL command from your command line.
