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.
