Likely Causes
  1. The current statement triggered connection_failure, which PostgreSQL classifies as SQLSTATE 08006.
  2. Application SQL, parameter values, or transaction state are incompatible with PostgreSQL rules for connection failure.
  3. Environment differences (schema, permissions, or runtime settings) exposed this 08006 condition in production flow.
How to Fix It
1
Capture full query text, bind values, and transaction context for SQLSTATE 08006.
2
Reproduce connection_failure 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 failure.
5
Deploy and verify SQLSTATE 08006 no longer appears in error telemetry.
