I don't recommend it, since concurrent inserts that arrive slightly
out of order (e.g. auto-incrementing sequence values) can now split
pages a second time -- they have no wiggle room.

There is an ALTER INDEX for this. It works with primary keys, even
though they're generally though of as constraints, not indexes.
