Thanks - this is what I was afraid of, but I may have to do this
Is there a good way to monitor what's in the cache?

You've probably got cron jobs that run late at night and blow out your
kernel disk cache by accessing a whole lot of non-Postgres stuff.
(A nightly disk backup is one obvious candidate.) The most likely
solution is to run some cron job a little later to exercise your
database and thereby repopulate the cache with Postgres files before
you get to work ;-)
