One additional thought - in an offline conversation I had with Robert Haas,
he had taken the position that any FDW was likely pulling values across a
wire protocol and then synthesizing postgres-looking statistics from that,
so going with cstring inputs was fine, possibly preferable. I'm
highlighting that we're now passing in NullableDatums in case he wanted to
object to that change.
