It seems pgagent cannot connect to the database, which might be because you didn't provide the required credentials. Make sure your .pgpass file is properly configured.

Assuming you're using the user postgres for pgAgent and that you have installed the extension in the database postgres :

$ sudo su - postgres
$ cd ~
$ nano .pgpass

Insert the following text and save the document:

localhost:5432:*:postgres:[postgres_password]

This line basically tells the database connection to use the given password for the user postgres to connect to any ( * ) database on the server localhost listening on the port 5432 .

Once you're done with the .pgpass, give the file the proper permissions:

$ chmod 0600 .pgpass

You might need to restart pgAgent (not sure if it's necessary):

$ pgagent hostaddr=localhost dbname=postgres user=postgres
