Thanks Michael! Tests of injection points with injection points are neat :)
Alvaro, here’s the test for multixact CV sleep that I was talking about on
PGConf.
It is needed to test [0]. It is based on loaded injection points. This

It is OK to do a detach before a wakeup. Noah has been relying on
this behavior in an isolation test for a patch he's worked on.

I've tried to rebase my test of CV sleep during multixact generation[0]. I used
it like this:
INJECTION_POINT_PRELOAD("GetNewMultiXactId-done");
