php - postgresql max execution time

Is there开发者_高级运维 an option to use with PostgreSQL Functions in PHP, so you can specify a maxim execution time for a query ? I don't want to enable this from the config file because only certain queries need to be restricted.

run from php a query before the main query

like

SET statement_timeout TO 5000;

You can use set_time_limit() According to PHP doc:

When called, set_time_limit() restarts the timeout counter from zero. In other words, if the timeout is the default 30 seconds, and 25 seconds into script execution a call such as set_time_limit(20) is made, the script will run for a total of 45 seconds before timing out.
