Yes. I initially thought this code was kept intentionally because
some older PostgreSQL versions supported unlogged materialized views,
and even the latest psql might need to display them. However,
this isn't the case. Unlogged materialized views were added and
removed before the v9.3 release and were never supported in
any official release. So there seems no need to keep this code.
