This an old question.
psql suppose that table "test" is a view because it checks for pg_class.relhasrules and it prints "view?"
if the value is TRUE and the value is if there's a rule for the table.
The only way to distinguish a table from a view is the pg_get_viewdef.
Some time ago I suggested to use pg_get_viewdef('tablename') to check for views
to print "view or table" instead of "view?".
I made a patch to my psql and it now recognize views perfectly and I can display
only tables using \d and/or only views using \v
