Uh, no, not really. TG_OP is a local variable in the trigger function; it's not visible from elsewhere. > But what if a trigger calls a function that calls a 2nd function via the "PERFORM" command?

No. Doesn't really matter whether you use PERFORM or not. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
