I think that's not tenable. Even if you limit the discussion to the
postgres_fdw, some queries against past version will stop working
against new version (keywords changes, catalogs, default settings, etc).

I don't think you want to embed a full parser of every supported FOREIGN
version of PostgreSQL inside the postgres_fdw code, so I think the text
of the view needs to be an opaque string.
