Subject: [PATCH 7/8] Avoid code duplication in map_partition_varattnos()
MIME-Version: 1.0
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: 8bit
Code to map attribute numbers in map_partition_varattnos() duplicates
what convert_tuples_by_name_map() does. Avoid that.
Amit Langote, pointed out by Álvaro Herrera.
