Summary
Fixes the Postgres state adapter so
setIfNotExists()can claim a cache key whose existing row has expired.Previously the method used
ON CONFLICT DO NOTHING, so an expired row inchat_state_cachestill blocked acquisition until a separate cleanup deleted it. That diverged from the memory adapter behavior and from the expected lease semantics for cache-backed coordination.The new query keeps active rows protected, but replaces rows whose
expires_atis in the past.Validation
