commit    b2e4399baaa805a046b7ffa155c666c80bbf8429
Author:   Robert Haas <rhaas@postgresql.org>
Date:     Wed May 17 18:31:48 2017 +0000
First released in: 10.0

    Code review for make_partition_op_expr.
    
    It's better to use the actual keynum here rather than 0, because
    someday someone might try to make list partitioning work with
    multiple partitioning columns.
