OK, cool. I'll try to get that into the tree once v18 opens up. I
can see that GetNewMultiXactId() opens a critical section. I am
slightly surprised that you need both the SQL function
injection_points_load() and the macro INJECTION_POINT_LOAD().
Wouldn't one or the other be sufficient?
The test takes 20ms to run here, which is good enough.
+ INJECTION_POINT_LOAD("GetNewMultiXactId-done");
[...]
+ INJECTION_POINT("GetNewMultiXactId-done");
[...]
+ INJECTION_POINT("GetMultiXactIdMembers-CV-sleep");
Be careful about the naming here. All the points use lower case
characters currently.
