pgsql: Adjust more backend functions to return OID rather than void.

Adjust more backend functions to return OID rather than void.

This is again intended to support extensions to the event trigger
functionality. This may go a bit further than we need for that
purpose, but there's some value in being consistent, and the OID
may be useful for other purposes also.
