> Disallow it in table definitions, but allow it in domain definitions... Those two cases are not hard, because in those scenarios the parser knows it is expecting a type specification. The real problem is this syntax for typed literals: typename 'string' which occurs in ordinary expressions. So when you see "name(" you aren't real sure if you're seeing the start of a function call or the start of a typed-literal construct. And it's very hard to postpone that decision until you see what comes after the right paren. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
