True. In the "Table classname.tablename" case, there is no requirement
for quotes in English, but there is for technical reasons. Imagine:
Table My class.My table
Looks kind of strange without quotes:
Table "My class"."My table"
Still looks strange, but better. :-)

As I saw, Peter was suggesting to always use quotes to match the message
guidelines:
Table "myclass"."mytable"
or
Table "mytable" (Class "myclass")
However, I have not seen anyone prefer that except Peter so that will
not be adopted unless Peter can find more people that agree with him.
So it seems we can either go with no quotes, or smart quotes (which my
patch implemented). I feel my patch does the best of both worlds, by
quoting as needed, and as the psql \d commands actually require anyway,
and as used by pg_dump and in SQL queries.
