We have touched upon this point several times during the development of this patch. The main problem is that you need to distinguish no collation from the default collation, so they can't both be OID zero. Another problem is that if you assume OID zero means default, finding bugs in the expression tree analysis would be really hard. It would be like saying, oh, we have type OID zero, let's make it text and proceed. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
