That 9.0 change was far less invasive than this: it only added a count
field to SELECT and CTAS result tags. Quite aside from the fact that
the tag name stayed the same, in the SELECT case it's unlikely anyone
would have checked the tag at all rather than just testing for
PQresultStatus() == PGRES_TUPLES_OK. So it was basically only changing
the result for *one* command type. I don't think it's a good basis for
arguing that this patch won't cause problems.
