I didn't searched for, but I guess all of the end-side callback of all begin-end type callbacks are not called on exception. Additional PG_TRY level wouldn't be acceptable for performance reasons. What we (pg_hint_plan people) want is any means to know that the top-level function is exited, to reset function nest level. It would be simpler than calling end callback at every nest level. regards. -- Kyotaro Horiguchi NTT Open Source Software Center
