Oh, one other thought is that the function body has to be
conditionalized on HAVE_READLINK (the fact that you forgot that
somewhere else isn't an excuse for not doing it here).  IIRC,
only the two built-in tablespaces can exist when not HAVE_READLINK,
so it seems sufficient to handle those cases and then PG_RETURN_NULL
(or maybe throw error) when not HAVE_READLINK.
