That all looks OK, but it sounds like the stats collector is not running
anyway. Have you checked with "ps" to see if the postmaster has a
couple of child processes calling themselves stats buffer and stats
collector? (You may need to say "ps aux" or "ps -ef" depending on
platform to see these labels rather than generic "postmaster" labels.)

If it's not running, look in the postmaster log right after restarting
the postmaster; there may be a message there about why not.
