commit    591d404b9cd2c562bfe7fe60d76988d49b5ba2b1
Author:   Tom Lane <tgl@sss.pgh.pa.us>
Date:     Thu Dec 12 00:08:16 2019 +0000

    Add readfuncs.c support for AppendRelInfo.
    
    This is made necessary by the fact that commit 6ef77cf46 added
    AppendRelInfos to plan trees.  I'd concluded that this extra code was
    not necessary because we don't transmit that data to parallel workers
    ... but I forgot about -DWRITE_READ_PARSE_PLAN_TREES.  Per buildfarm.
