That looks like an oversight of 4a39f87acd6e to me. A static buffer
in this context is not adapted.

This forces a new allocation for each message printed vs a set of
resets after one allocation is done. This change is not going to be
entirely free as done in the patch, so should we worry about that?
Perhaps it would be cheaper to allocate a PQExpBuffer in each CState,
and just reuse it in this routine?
