Just as a followup (and I already posted this on the pgsql-admin thread),
the check_postgres script now has a specific check for this very case.
It simply checks the age of entries in pg_prepared_xacts and gives
a warning if the number is at or over the given threshhold (defaults
to 1 second). I'm still a heavy +1 on making the default Postgres
configuration value 0, but hopefully this will help.
