I've reworked the patch a bit to remove the "excessive bloat with low
fillfactors when local space is available" issue that this parameter
could cause - local updates are now done if the selected page we would
be inserting into is after the old tuple's page and the old tuple's
page still (or: now) has space available.
Does that alleviate your concerns?
