I noticed that if I use... IF (TG_OP = 'DELETE' AND OLD.myColumn) THEN -- Do something END IF; when an insert happens, I get an error that 'OLD' has not been assigned. I would of thought that the control structure would just ignored the rest of the 'if' statement if the first part (TG_OP) was false. Does this mean I have to branch out my control structures if I want better speed? If the first part of the 'if' is rarely true, then I might as well put the second control within the first. -Nick -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
