Postgres14 change the default data directory

1. What is the issue? Please be detailed.

We have upgraded to the latest ODK Central with the Postgres infrastructure change to Postgres 14. We would like to use a different data directory for Postgres which will be backed up rather than the default /var/lib/.... directory.

2. What steps can we take to reproduce this issue?

Is there a way to have a different postgres data directory than the default?
Where is this set up?
