Postgresql is supposed to cope with file descriptor limits quite happily, as long as the OS actually restricts the number of files a process can have open. If it doesn't restrict the number, just falls over if there's too many, there's a postgresql configuration option to limit it (max_files_per_process, I think). What OS are you on, and what was the catastrophe?
