Uh, what did your CREATE TYPE command look like, exactly? This sounds like you specified a default value for the datatype. Maybe you need to show us your datatype's I/O functions, too. Since this works perfectly fine for the standard variable-length datatypes, it's hard to arrive at any other conclusion than that your custom datatype code is erroneous. But there's not enough info here to figure out just what is wrong with it. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
