OK, thanks. I still don't really like allowing this, but I can see that compatibility with other systems has some value here, and if nobody else is rejecting these cases, maybe we shouldn't either. So I'll hold my nose and change my vote to canonicalizing rather than rejecting outright. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
