Log message:
    Several fixes for hash indexes that involve changing the on-disk index
    layout; therefore, this change forces REINDEX of hash indexes (though
    not a full initdb).  Widen hashm_ntuples to double so that hash space
    management doesn't get confused by more than 4G entries; enlarge the
    allowed number of free-space-bitmap pages; replace the useless bshift
    field with a useful bmshift field; eliminate 4 bytes of wasted space
    in the per-page special area.
