In this regression test we check the `DROP SCHEMA public CASCADE;` for removing the extension objects stored in that schema. The problem is if at the same moment we're running a background job it will lead to a deadlock because the scheduler maintain information about each execution in the metadata tables that should be part of the cascade schema removal. Forced stop the background jobs and also terminate any running job. https://github.com/timescale/timescaledb/actions/runs/9424506293/job/25964852620
