Add a "relistemp" boolean column to pg_class, which is true for temporary
relations (including a temp table's indexes and toast table/index), and
false for normal relations. For ease of checking, this commit just adds
the column and fills it correctly --- revising the relation access machinery
to use it will come separately.
