I am working on this new patch and that is how I have been implementing it.  If
the eventProc function returns FALSE for creation events (not destruction
events), the libpq call that triggered it will fail.  For instance: for the
creation of result objects "PGEVT_RESULTCREATE", I am clearing the result and
returning an error value.

I think that is the expected behavior when one calls PQexec and an out-of-memory
failure occurs.
