<para>
Prevent non-key-field row updates from locking foreign key rows
(AlvaroAacute;lvaro Herrera, Marti Raudsepp, Alexander Shulgin,
Noah Misch and Andres Freund)
</para>
<para>
This improves concurrency and reduces the probability of deadlocks.
UPDATEs on non-key columns use the new SELECT FOR NO KEY UPDATE lock
type, and foreign key checks use the new SELECT FOR KEY SHARE lock mode.

Add cache of local locks (Jeff Janes)

This speeds lock release at statement completion in transactions
