Likely Causes

Capture full query text, bind values, and transaction context for SQLSTATE 23P01.
2
Reproduce exclusion_violation in staging with the same schema version and connection settings.
3
Inspect pg logs and execution plan details to isolate the exact failing clause or object.
4
Apply a targeted fix (query rewrite, schema migration, or transaction-order change) for exclusion violation.
5
Deploy and verify SQLSTATE 23P01 no longer appears in error telemetry.
