From a fresh server restart I have one process that will run one

dump from ProcessExplorer. I have highlighted the relevant lines with
****. Also attached is the current postgresql log after a server
restart. You can see from the log that about every 70 seconds there is
an entry "WARNING: pgstat wait timeout". This will go on forever.
Apparently the stats collector has gotten stuck in a loop and is failing
to update the stats file. The 'wait timeout' bleats are probably coming
from the autovacuum launcher process, which is waiting for an up-to-date
stats file to appear. Can you get a stack trace from the stats
collector process?

Sorry for the delayed response to this but I just had too many fires to
put out. In the mean time, this problem seems to have cured itself. I
rebooted my computer yesterday (Windows XP), the postgres service
started and I'm no longer having an issue. I had not rebooted since I
upgraded to 8.4 but it seems to have done the trick. Previously in
8.3.7 I would have this problem every time I would reboot.
