Thanks!

Interestingly, previously having INJECTION_POINT_PRELOAD() was not enough.
But now both INJECTION_POINT_LOAD() or injection_points_load() do the trick, so for me any of them is enough.

My test works with current version, but I have one slight problem, I need to call
$node->safe_psql('postgres', q(select injection_points_detach('GetMultiXactIdMembers-CV-sleep')));
Before
$node->safe_psql('postgres', q(select injection_points_wakeup('GetMultiXactIdMembers-CV-sleep')));

Is it OK to detach() before wakeup()? Or, perhaps, can a detach() do a wakeup() automatically?
