Fixes for single-page hash index vacuum.
Clear LH_PAGE_HAS_DEAD_TUPLES during replay, similar to what gets done
for btree. Update hashdesc.c for xl_hash_vacuum_one_page.
Oversights in commit 6977b8b7f4dfb40896ff5e2175cad7fdbda862eb spotted
by Amit Kapila. Patch by Ashutosh Sharma.
Bump WAL version. The original patch to make hash indexes write-ahead
logged probably should have done this, and the single page vacuuming
patch probably should have done it again, but better late than never.
