Log message:
Reimplement hash index locking algorithms, per my recent proposal to
pghackers. This fixes the problem recently reported by Markus Kr�utner
(hash bucket split corrupts the state of scans being done concurrently),
and I believe it also fixes all the known problems with deadlocks in
hash index operations. Hash indexes are still not really ready for prime
time (since they aren't WAL-logged), but this is a step forward.

TIP 9: the planner will ignore your desire to choose an index scan if your
joining column's datatypes do not match
