Unfortunately, the problem isn't really the additional disk space it
would require.  The problem is the additional performance hit and
memory overhead, as the catalog names are part of the internal
syscache.

I understand your frustration, but given those problems I don't think
that postgres will increase the default NAMEDATALEN value any time
soon, even though it's in contradiction with the SQL standard.
