I'm afraid *NOT*. You can write a script / cronjob for this task. The script will check postgresql periodically and will restart posgresql daemon in case the configuration was changed. You can use `stat` command (try `stat --help`) to get the right information about file's modifcation. You should *check* if your configuration is valid before restart the daemon as any wrong modification can cause your server to stop :)

I know there's a tool that will do some tasks whenever a(ny) file in the system has been modified. But I can't remember the name of that tool.
