Wait a minute.   This patch changes the behavior so that
LockBufferForCleanup is applied to *every* heap page, not only the ones
where there are removable tuples.  It's not hard to imagine scenarios
where that results in severe system-wide performance degradation.
Has there been any real-world testing of this idea?

       choose an index scan if your joining column's datatypes do not
       match
