## Problem
The current test history format is a bit inconvenient:
- It stores all test results in one row, so all queries should include
subqueries which expand the test
- It includes duplicated test results if the rerun is triggered manually
for one of the test jobs (for example, if we rerun `debug-pg14`, then
the report will include duplicates for other build types/postgres
versions)
- It doesn't have a reference to run_id, which we use to create a link
to allure report
Here's the proposed new format:
```
id BIGSERIAL PRIMARY KEY,
parent_suite TEXT NOT NULL,
suite TEXT NOT NULL,
name TEXT NOT NULL,
status TEXT NOT NULL,
started_at TIMESTAMPTZ NOT NULL,
stopped_at TIMESTAMPTZ NOT NULL,
duration INT NOT NULL,
flaky BOOLEAN NOT NULL,
build_type TEXT NOT NULL,
pg_version INT NOT NULL,
run_id BIGINT NOT NULL,
run_attempt INT NOT NULL,
reference TEXT NOT NULL,
revision CHAR(40) NOT NULL,
raw JSONB COMPRESSION lz4 NOT NULL,
```
## Summary of changes
- Misc allure changes:
- Update allure to 2.23.1
- Delete files from previous runs in HTML report (by using `sync
--delete` instead of `mv`)
- Use `test-cases/*.json` instead of `suites.json`, using this directory
allows us to catch all reruns.
- Until we migrated `scripts/flaky_tests.py` and
`scripts/benchmark_durations.py` store test results in 2 formats (in 2
different databases).
