src/include/access: hash.h
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.
