If it's an array (i.e. perhaps a column declared as text[]), then maybe it's not that wrong, as has been said elsewhere on the thread (but I would agree with you that if there's no specific reason to do things that way, it's probably less right than your contractor wants to admit). If it is actually a single text column with comma separated values, and the splitting is done client-side, I'd hazard that you're probably right in placing blame in the contractor. -- Alvaro Herrera http://www.CommandPrompt.com/ The PostgreSQL Company - Command Prompt, Inc.
