Well, an elog callback is certainly the wrong place for that. Even if
it looked to see whether the elog call was ERROR or not, an ERROR is no
longer necessarily unrecoverable --- it might be caught inside a plpgsql
exception block, for example, and not really be an error at all from the
perspective of calling code.
The right way would be to use PG_TRY to catch the exception as it
propagates out to your own level of control.
