Yeah, I intend to commit what I have after I finish cleaning up a few
loose ends (just found a bug with CLOBBER_CACHE_ALWAYS), and then we
can take a look at making autovacuum play with it. I envision three
or four commits before flatfiles.c can disappear.

Yeah. That's not in the patch I sent last night, but the OID index has
to become nailed too in order to allow removing FindMyDatabaseByOid.
However, I'm not sure that the AV launcher could touch it --- were
you thinking that would be important?
