Hmm, I typically use a pair of
"ALTER TABLE table DISABLE TRIGGER USER;"/
"ALTER TABLE table ENABLE TRIGGER USER;"
per almost every relation when loading a dump, other than that there's
only the initial db creation code (lots of plpgsql triggers and a couple
immutable functions) and then using temp tables for complicated queries.
Thanks again for looking into this,
