Spawning apache every second totally hammers low-power systems. The
important thing here is to have the postgres checker bail the run script
_before_ starting apache so if postgres isn't up and ready, you only incur
the hit of rerunning a few lines of shell and a light-weight check program,
not spooling up a web server.
