Well, you need to find out why. Turning on query logging (see
log_statement) would probably be a good first step --- it'd help
you determine if there's a specific query or queries causing it.
Also, have you tried pg_ctl stop -m fast instead of a reboot?
(If that doesn't work, it'd also be interesting to see if -m immediate
does work.)
