Get rid of any toast table when converting a table to a view.

Browse Source 
Also make sure other fields of the view's pg_class entry are appropriate
for a view; it shouldn't have relfrozenxid set for instance.

This ancient omission isn't believed to have any serious consequences in
versions 8.4-9.2, so no backpatch.  But let's fix it before it does bite
us in some serious way.  It's just luck that the case doesn't cause
problems for autovacuum.  (It did cause problems in 8.3, but that's out
of support.)
