I am thiking the vacuum_cleanup_index_scale_factor existance in a PG 14
postgresql.conf will throw an error, unlike 13.x, so I do think we need
to mention this so people will know to remove it from their
postgresql.conf before upgrades, right? I don't think the PG 13.3
release note mention really makes it clear it has to be removed. In a
dump/restore, so we retain the reloption
vacuum_cleanup_index_scale_factor and just ignore it, or drop it on
restore? I am hoping it is the later.
