Modified files:
src/backend/access/hash: hashinsert.c hashovfl.c hashpage.c
src/include/access: hash.h
Log message:
Preliminary cleanup for hash index code (doesn't attack the locking problem
yet). Fix a couple of bugs that would only appear if multiple bitmap pages
are used, including a buffer reference leak and incorrect computation of bit
indexes. Get rid of 'overflow address' concept, which accomplished nothing
except obfuscating the code and creating a risk of failure due to limited
range of offset field. Rename some misleadingly-named fields and routines,
and improve documentation.
