You sure you aren't just trading one misbehavior for another? The
change in PQmakeEmptyPGresult, for example, just moves the core dump
somewhere else, unless you find reasonable fallbacks for *all* its
callers (including applications you don't have the source code for,
but in any case including every one of the calls in libpq).
