This probably means you need to rethink your database design, it's a process called normalization, I won't go into it right now, but you should check it out. For example, a customer table with all your customers in it with a separate call information table that links call info to customers. > Now, the question is: Is there a way to know if a given table exist? > Besides doing a direct query to it, of course, as I think that would > be too much of a dinamite-fishing way of doing it. You can get a query to do this if you go into psql -E, and use the \dt command, actually with -E on the command line, all of the \ commands will print out the queries they are using. -- chalk slayer
