Fixes the deadlock visible in https://github.com/TheThingsNetwork/lorawan-stack/actions/runs/5462658722/jobs/9942792699 .

Changes

• Disable the session reset check while using the pgx driver until we have a clear solution to the background reader concurrency issues.

Testing

Regressions

pgx should already have other checks in place for connection closure detection, and as such this shouldn't cause any extra regressions.
