It's not that easy to make a 100% backwards compatible view for a system
catalog. The main sticking point is the OID column; see recent problems
with pg_roles' OID column for an example. On the whole I don't think
renaming pg_tablespace and inserting a mostly-compatible view would be
a net advance.
More generally, I don't see that this particular incompatibility in
the system catalogs is worse than many others that we've perpetrated.
