## Problem We want to be able to test how our infrastructure reacts on segfaults in Postgres (for example, we collect cores, and get some required logs/metrics, etc) ## Summary of changes - Add `trigger_segfauls` function to `neon_test_utils` to trigger a segfault in Postgres - Add `trigger_panic` function to `neon_test_utils` to trigger SIGABRT (by using `elog(PANIC, ...)) - Fix cleanup logic in regression tests in endpoint crashed
