Were you foolish enough to remove pg_log as well? If so, all your
past transactions now appear uncommitted ...
Bryan White had this same problem awhile ago --- see
http://www.arcamax.com/pg_check/ for the tool he developed.
Bear in mind though that you cannot get back a consistent state
of the database, because the info about which transactions committed
and which didn't is gone. If you have a somewhat recent backup, it's
probably better to revert to that.
