Hi all,
I don't remember how many times in the last few years when I've had to hack the backend to produce a test case that involves a weird race condition across multiple processes running in the backend, to be able to prove a point or just test a fix (one recent case: 2b8e5273e949). Usually, I come to hardcoding stuff for the following situations: - Trigger a PANIC, to force recovery. - A FATAL, to take down a session, or just an ERROR. - palloc() failure injection. - Sleep to slow down a code path. - Pause and release with condition variable.
+1 for the feature.
TWIMW, here[1] is an interesting talk from pgconf.in 2020 on the similar topic.
