## Problem We started to store test results in a new format in https://github.com/neondatabase/neon/pull/4549. This PR switches scripts to query this db. (we can completely remove old DB/ingestions scripts in a couple of weeks after the PR merged) ## Summary of changes - `scripts/benchmark_durations.py` query new database - `scripts/flaky_tests.py` query new database
