I have converted my generic trigger to use EXECUTE ... USING. I need to convert all NEW values to a text array, retaining their ordinal position. avals(hstore(NEW)) doesn't seem to do that: NEW: (5,name5,1000,,,2) avals(hstore(NEW)): {5,name5,2,1000,NULL,NULL} The best I can come up with is a JOIN with information_schema.columns. -- Best Regards, Tarlika Elisabeth Schmitz -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
