The actual error you're getting is probably confusion between variable names and literal objects. Especially in older postgres try not to have variable names that happen to be the same name as tables or columns. I can't tell for sure since the the whole function isn't posted. merlin -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
