when it happens, make sure to query pg_locks and see what is going on
there lock issues are not supposed to manifest on a commit, which
releases locks, but you never know.  There have been reports of
insonsistent lock ups on windows (espeically multi-processor) which
you might be experiencing. Make sure you have the very latest version
of pg 8.1.x.  Also consider checking out 8.2 and see if you can
reproduce the behavior there...this will require compiling postgresql.
