I don't think it's a good idea to deliberately leave the state of the
standby different from the state of the master on the theory that it
won't matter. I feel like that's something that's likely to come back
to bite us.
Giving LockAcquireExtended() an argument that causes some
AccessExclusiveLocks not all to be logged also seems pretty ugly,
especially because there are no comments whatsoever explaining the
rationale.
