-   * PostgreSQL adheres strictly to the SQL-92 standard and requires that when
-   * using DISTINCT or GROUP BY conditions, fields and expressions that are
-   * ordered on also need to be selected. This is a best effort implementation
-   * to handle the cases that can be automated by adding the field if it is not
-   * yet selected.
-   *
-   * @code
-   *   $query = db_select('example', 'e');
-   *   $query->join('example_revision', 'er', 'e.vid = er.vid');
-   *   $query
-   *     ->distinct()
-   *     ->fields('e')
-   *     ->orderBy('timestamp');
-   * @endcode
-   *
-   * In this query, it is not possible (without relying on the schema) to know
-   * whether timestamp belongs to example_revision and needs to be added or
-   * belongs to node and is already selected. Queries like this will need to be
-   * corrected in the original query by adding an explicit call to
-   * SelectQuery::addField() or SelectQuery::fields().
-   *
-   * Since this has a small performance impact, both by the additional
-   * processing in this function and in the database that needs to return the
-   * additional fields, this is done as an override instead of implementing it
-   * directly in SelectQuery::orderBy().
