I flat do not understand the user definitions for a PostgreSQL server, and my limited experience with running Pg has been a result more of trial and error than understanding.
For example, I have a server which is running Apache. How must I set upt pg_hba.conf so the Apache user can access Pg? Likewise for Mailman, etc.
Can anyone point me to a good cookbook example or a detailed discussion of a set up for allowing access to server services as well as human users?
Thanks so much.
Best regards,
-Tom
