Unless I'm misunderstanding the documentation, you create the trigger on the "ddl event" not a table. The events are ddl_command_start, ddl_command_end, table_rewrite and sql_drop. I have not used this feature, but it seems like you would just need one function.

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.
