By my math, I'll need to vacuum once every hour or so.  Cron, here I
come.

vacuumdb --table cached_metrics loggerithim

I assume I do not need a --analyze, since that table has no indexes.
Should I vacuum the entire DB?

Any other settings I should look at?  Note that I'm not necessarily
having any problems at present, but one can always tune.  This DB is
used with a web app (mod_perl/DBI) at the moment, but is moving to a
Java Swing client, which will give me much more data about performance.
