Re: Way to quickly detect if database tables/columns/etc. were modified?

I have tried using an event trigger to detect table creation (ie: tg_event_audit_all ) however, that does not parse the schema_name and objid

as does pg_event_trigger_dropped_objects(), so I am not sure that is a practical way to audit.

Event triggers seem like the most promising suggestion so far (given that I only really need to know that something has changed, not necessarily what).

Still, I was hoping for a solution that doesn't rely on modifying the database at all, i.e. something built into Postgres, but it's pretty clear from everyone's answers nothing like this exists. (I wasn't looking for a creation date, exactly, because I'd want to know when something was modified, too).
