Hmm. That is how it probably *should* work, but at the moment the timestamptz_zone() function actually outputs a character string! That is a holdover from previous versions which did not have a "no zone" timestamp; it would seem now to be more appropriate to output a no-zone timestamp. I'll look at changing this in my upcoming patch set... - Thomas ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/users-lounge/docs/faq.html
