SELECT macavity_arm('before_abort', 'error');
ERROR:  macavity: action "error" is not supported at fault point "before_abort"
DETAIL:  PostgreSQL has no pre-abort hook; the abort is already in progress when this point is reached, so raising an error there would escalate to FATAL.
HINT:  Use action "crash" or "delay" at "before_abort", or arm "error" at "before_commit".
