      In looking at the 7.1beta1 code for JDBC, I noticed that support was · 4ce226ee

      added to support character set encodings.  However I noticed that the
      encoding that is used isn't obtained from the DB.  Since Java uses
      unicode UCS2 internally the character set encoding is used to translate
      strings from/to the DB encoding.  So it seems logical that the code
      would get the encoding from the DB instead of the current method of
      requiring the user pass it as a parameter.
      
      Attached is a patch that gets the DB encoding from the DB in the same
      manner as is done in libpq/fe-connect.c.  The patch is created off of
      the latest CVS sources (Connection.java version 1.10).

      Revise lock manager to support "session level" locks as well as "transaction · 6cc842ab

      level" locks.  A session lock is not released at transaction commit (but it
      is released on transaction abort, to ensure recovery after an elog(ERROR)).
      In VACUUM, use a session lock to protect the master table while vacuuming a
      TOAST table, so that the TOAST table can be done in an independent
      transaction.
      
      I also took this opportunity to do some cleanup and renaming in the lock
      code.  The previously noted bug in ProcLockWakeup, that it couldn't wake up
      any waiters beyond the first non-wakeable waiter, is now fixed.  Also found
      a previously unknown bug of the same kind (failure to scan all members of
      a lock queue in some cases) in DeadLockCheck.  This might have led to failure
      to detect a deadlock condition, resulting in indefinite waits, but it's
      difficult to characterize the conditions required to trigger a failure.
