Thanks a lot, but I still getting an error message like this: ERROR: cache lookup failed for type 0 What is wrong? -----Original Message----- From: pgsql-hackers-owner@xxxxxxxxxxxxxx [mailto:pgsql-hackers-owner@xxxxxxxxxxxxxx] On Behalf Of Tom Lane Sent: Lunes, 07 de Noviembre de 2005 05:17 p.m. To: Cristian Prieto Cc: pgsql-general@xxxxxxxxxxxxxx; pgsql-hackers@xxxxxxxxxxxxxx Subject: Re: [HACKERS] Help with Array Function in C language...
