Check, though I assume we're not expecting PQsetInstanceData to
propagate to previously created PGresults?

Should be libpq-something.  I was considering libpq-hooks.h or
libpq-events.h, but libpq-callback.h would be OK too.

No, of course not.  What I was imagining was that the resultcreate
callback would call PQresultSetInstanceData.
