Hi, is it possible to enforce naming convention in pg? Can I create a trigger that runs when a new object is created and see if its name is in an expected format and if not reject it? I had to create a new schema 'zref' storing some of our tables to conceptually separate them but I want to make sure that when we create new tables we can't have the same table name in 'zref' and 'public'. Thanks for the help. Balázs
