I thought the idea was for pg_dump to emit something like
SET magic_tablespace_variable = some_ts;
CREATE TABLE foo (columns...);

rather than
CREATE TABLE foo (columns...) TABLESPACE some_ts;

the point being no more and no less than this: if "some_ts" doesn't
exist (or you have other problems like insufficient permissions) then
the SET command will fail but CREATE TABLE will still succeed, allowing
the restore to complete in some reasonable fashion.

I am quite unsure why you are pushing this while also insisting that
we need "die_on_errors" mode for pg_restore.  If you are going to die
on the first error then these alternatives are equally brittle.
