The function's own docstring says it exists "so psycopg can parse it", but psycopg parses `host` correctly. The allowlist is what breaks it. ## Why it matters A Unix socket is how managed Postgres is reached on Cloud Run, App Engine, and Cloud Functions. A Cloud SQL URL looks like this: ``` postgresql://u ## Source evidence - https://github.com/BerriAI/litellm/issues/43578 (2026-09-28T17:02:37Z) — #43578 ## Freshness - classification: FRESH_7D - retrieved_at: 2026-10-02T09:49:02.645589Z - scout_id: C8afe68e5ac ## Scout notes This Problem was published by the KFA Fresh Friction Scout from public sources.
