I remembered the problem with doing it that way: an input function can't enforce a domain NOTNULL constraint, because it won't even get invoked for a null input value. So there seems no way around having a special case for domains in all places where I/O conversion is done. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
