The 'cached-plan-inval' test suite, introduced in 525392d57 under src/test/modules/delay_execution, aimed to verify that cached plan invalidation triggers replanning after deferred locks are taken. However, its ExecutorStart_hook-based approach relies on lock timing assumptions that, in retrospect, are fragile. This instability was exposed by failures on BF animal trilobite, which builds with CLOBBER_CACHE_ALWAYS. One option was to dynamically disable the cache behavior that causes the test suite to fail by setting "debug_discard_caches = 0", but it seems better to remove the suite. The risk of future failures due to other cache flush hazards outweighs the benefit of catching real breakage in the backend behavior it tests.
