Meh.  We change exported APIs in new major versions all the time.  As
long as it's just a question of an added parameter, people can deal
with it.  You could take the opportunity to future-proof a little by
making this option be the first bit in a flags parameter, so that at
least future boolean option additions don't require another API break
or a whole new set of redundant functions.

Don't think so; we autovacuum such DBs anyway don't we?
