I just tried it on 8.2, and it seems that renaming the table doesn't rename the primary key index - you have to do it explicitely. > There's a second table that has a foreign key constraint on > service_id_pkey, so do i need to drop that constraint first, rename the > first table, then re-create the constraint using the new pkey name? Without having tried it, I don't think so - my understanding is that database objects are represented internally as OIDs, so renaming the object changes only the name and not the OID. --Ray. ---------------------------------------------------------------------- Raymond O'Donnell Director of Music, Galway Cathedral, Galway, Ireland rod@iol.ie ----------------------------------------------------------------------
