It doesn't have to make its way into the postgresql daemon itself -- in fact since some people like tuning the
vacuuming,it makes more sense to make this a daemon. No, my suggestion is simple that some sort of auto-vacuumer be
compiledas a stand-alone app and included in the standard postgresql tar.gz file, and the install instructions
recommendthe site adding it as a cron job.  

On linux, it'd be good if the RPM install it automatically (or else it ran as a mostly-asleep daemon) because so many
ofthe Linux/Postgresql users we see have just no clue about Postgresql, and no intention of reading anything. 

Just an FYI, a message I received today from the postmaster at a major telco about their postgresql experience:
