pgsql: Split out permissions

Coming up in community.postgresql 4.0.0 using priv with the
postgresql_user be removed, and we are encouraged already now to
start using the postgresql_privs module.

This works atleast down to community.postgresql 2.0.0, possibly
lower. Seems like a good time to pin a minimum requirement for this
dependency.

This should also take care of some outstanding issues with
installing on postgres-15 (ansible-collections#928)
