Well, you'd have to use the same cheat that's used for selectivity estimation functions, triggers, I/O functions and everything else that deals in internal datatypes: declare the function as taking and returning OPAQUE. This is moderately annoying but I don't think there's anything really wrong with it in practice. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
