Don't bother to attach column name lists to RowExprs of named types. If a RowExpr is marked as returning a named composite type, we aren't going to consult its colnames list; we'll use the attribute names shown for the type in pg_attribute. Hence, skip storing that list, to save a few nanoseconds when copying the expression tree around.
