My extension has a config table that is dumped by pg_dump and populated by pg_restore.
However, this table has triggers on it that I would like not to do anything if the table is being populated by pg_restore. I want the triggers to operate only if the user is manipulating the table directly after the database has been restored and is running.

Is there a way for my extension's trigger functions to return immediately when triggered by pg_restore?

Thanks.

You'd probably have to wrap your pg_dump/restore in some sort of script that can call the advisory locks, but I don't see why it wouldn't work. Then you'd have your triggers check if the advisory lock is held and skip whatever they do if so.
