Hi Michael, at the first glance it seems to be perfect. In addition it works even for arrays. Wow! :) Thank you very much, -- Csaba -----Original Message----- From: Michael Fuhr [mailto:mike@xxxxxxxx] Sent: Thursday, February 10, 2005 8:32 AM To: Együd Csaba Cc: pgsql-general@xxxxxxxxxxxxxx Subject: Re: Any functions to convert bit(5) to text?

That is, using the source type's output function to get a cstring that you pass to the target type's input function? Are there any potential problems with doing this? Is that how the PL/pgSQL RETURN trick works? It seems a handy way to cast one type to another when no built-in cast or function exists. -- Michael Fuhr http://www.fuhr.org/~mfuhr/ -- No virus found in this outgoing message.
