Likely Causes
  1. The current statement triggered connection_does_not_exist, which PostgreSQL classifies as SQLSTATE 08003.
  2. Application SQL, parameter values, or transaction state are incompatible with PostgreSQL rules for connection does not exist.
  3. Environment differences (schema, permissions, or runtime settings) exposed this 08003 condition in production flow.
How to Fix It

Capture full query text, bind values, and transaction context for SQLSTATE 08003.
2
Reproduce connection_does_not_exist 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 connection does not exist.
5
Deploy and verify SQLSTATE 08003 no longer appears in error telemetry.
