If you add a constraint using ALTER TABLE it will check existing data also. One option is you create a new table with the constraints and same column names then: insert into newtable values ( select * from oldtable) but again this will check for old data, but may be faster. -- Nilesh Govindarajan Facebook: nilesh.gr Twitter: nileshgr Website: www.itech7.com -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
