Oh, right.  Yes, we should do something about that.  I think we could
invent PQerrorField which is to PQerrorMessage as PQresultErrorField
is to PQresultErrorMessage.  The reason I didn't do so during the 7.4
cycle is that errors generated internally within libpq wouldn't have any
field information, at least not without significant hacking on the libpq
sources.
