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.
