I was under the impression that this was extending PQsetvalue to let it
be used in previously unsupported ways, ie, to modify a server-returned
PGresult. That's a feature addition, not a bug fix. I'm not even sure
it's a feature addition I approve of. I think serious consideration
ought to be given to locking down returned results so PQsetvalue refuses
to touch them, instead. Otherwise we're likely to find ourselves unable
to make future optimizations because we have to support this
barely-used-by-anybody corner case.
