The existing auxiliary processes (in 8.4) and their entry points are
autovacuum (autovacuum.c, AutoVacLauncherMain)
bgwriter (bgwriter.c, BackgroundWriterMain)
walwriter (walwriter.c, WalWriterMain)
startup/recovery (xlog.c, StartupProcessMain)
You should probably compare the characteristics of these processes (when are they launched, how do they interface with the database, ...) to your requirements. Pick the best-matching candidate and start by copying what it does.
