Execution timeout using CLI

Hi, I just inherited a bunch of PHP code that interacts extensively with a postgresql database. Execution of this script can take many minutes - sometimes more than 30. The tables the script is running against grow continually, and recently the script has been timing out with this error: Fatal error: Maximum execution time of 300 seconds exceeded in dbbind.php on line 17 This script "require_once"s several other scripts. Once of these, itself, "require_once"s the dbbind.php script mentioned in the error above. Line number 17 looks like this: $t=pg_fieldtype($rs,$col); The original script is being invoked at the command line like this: /mm/php-cmdline-431/bin/php -f script_to_run.php My major question here is why am I timing-out? I thought CLI PHP would wait forever for execution? Do I need to set a timeout someplace for db operations? Overall, the problem has to do with poor system architecture and table locking. However I don't have the time to re-architect the entire system and am hoping there is a quick fix to prevent, or lengthen, the timeout. Any help is greatly appreciated.
