Обсуждение: Reduce the time to know trigger_file's existence

Hi, 

This is to reduce the 3-4 seconds delay that exists with the current implementation in postgres. As per the current implementation, the thread checks for the existence of the file every 5 seconds. If the file got created just 1 second after the sleep, there is a wait time of 4 seconds before we know whether the file is present or not. We intend to avoid this delay by using inotify().

PostgreSQL version number you are running: postgres 9.1.5

How you installed PostgreSQL: Downloaded and compiled the sources
