        Is the server running locally and accepting connections on that socket?

Check the PostgreSQL socket path?

Hey folks,

@Mukesh1328 It’s very old, could you upgrade Ansible or install the latest collection version using the ansible-galaxy command and try again if the socket investigation won’t help?

@chris your help is much appreciated in all of those topics, thanks for the contribution!

In the managed node it shows
/tmp/.s.PGSQL.5432

How can we tell ansible to pick this path?

Sure, We are planning to do the upgrade. thanks you for response @Andersson007

Perhaps you would need to write a task to find the socket path, however I’d suggest upgrading Ansible first — hopefully this won’t be needed.

You should check the postgresql collection version you are using too.

The current one has a ‘login_unix_socket’ keyword to specify a socket, this is perhaps what you are looking for :
