No, reltriggers is reliable as a disable-all-triggers mechanism; when
it's zero the code won't even look in pg_trigger. But you can't use it
to disable just some triggers. I think the bug you are remembering is
that there's always been a pg_trigger.tgenabled field, but it wasn't
always honored everywhere, so it was unreliable as a selective-disable
mechanism until some recent release (I don't recall which, but I'm
afraid 7.4 is too old).
