Description
Setting to minor because it seems to only affect 10.2.
It may be related to all or any or none of numerous diagnostics area issues, I don't have enough information to link them.
The first test case is more "natural" (uses the real KILL), and it fails very well for me, but still, it's not deterministic, run with --repeat if it doesn't fail right away. The alternative second test case uses the odd behavior of max_session_mem_used. The effect usually depends on the type of the build, either it causes the query look like it was killed (which this test case exploits to avoid the race condition), or it fails with a proper error message, then there will be no assertion failure.
