Adjustments to the btree fastpath optimization.
This optimization was introduced in commit 2b272734. The changes include
some additional comments and documentation, and also these more
substantive changes:
. ensure the optimization is only applied on the leaf node of a tree
whose root is on level 2 or more. It's of little value on small trees.
. Delay calling RelationSetTargetBlock() until after the critical
section of _bt_insertonpg
. ensure the optimization is also applied to unlogged tables.
Pavan Deolasee and Peter Geoghegan with some very light editing from me.
