Deferrable unique constraints are a new feature in PostgreSQL 9.0, so it shouldn't be working in 8.4. (And as a sidenote, a reminder that 8.4 will go end of life in just a couple of months, so if you aren't already planning an upgrade of your production environment, it's probably a good idea to start doing that, see http://www.postgresql.org/support/versioning/) -- Magnus Hagander Me: http://www.hagander.net/ Work: http://www.redpill-linpro.com/
