Re: postgres.h included from relcache.h - but removing it breaks pg_upgrade

Agreed, this looks sane to me.  However, I think the
VM_ALL_{VISIBLE,FROZEN} macros should remain in visibilitymap.h, since
they depend on the visibilitymap_get_status function (and pg_upgrade
doesn't use them).

There's a typo "maros" for "macros" in the new header file.  (Also, why
does the copyright line say "portions" if no portion under another
copyright?  I think we don't say "portions" when there is only one
copyright statement line.)
