A theory worth considering therefore is that this is a bug in whatever extension is providing those functions. If, as I suspect, you're running EDB's version of Postgres, you would be well advised to turn to them for support. regards, tom lane -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
