What version of the

destination-postgres

connector does not get the following error?

Failure in destination: You must upgrade your platform version to use this connector version. Either downgrade your connector or upgrade platform to 0.63.7

The knowledge sources only indicate **which versions require platform 0.63.7**, not which earlier versions are safe on older platforms. For

destination-postgres

, the changelog explicitly warns: > Version 2.3.0: “WARNING: You must upgrade to platform 0.63.7 before upgrading to this connector version.” [[Postgres changelog](https://docs.airbyte.com/integrations/destinations/postgres#changelog)] So: - Any

destination-postgres

version ≥ 2.3.0 (e.g. 2.3.0, 2.4.0, 2.4.3, etc.) can trigger the error on platforms older than 0.63.7. [[Postgres changelog](https://docs.airbyte.com/integrations/destinations/postgres#changelog); [GitHub issue](https://github.com/airbytehq/airbyte/issues/54691)] - The docs do not explicitly state which exact earlier version (e.g. 2.2.x or below) is guaranteed not to show this error; they only imply that versions before 2.3.0 don’t have the 0.63.7 requirement. Based on the available information, the safest general rule is: > Use a

destination-postgres

version lower than 2.3.0 if you cannot upgrade your Airbyte platform to ≥ 0.63.7. However, the knowledge sources do not name a specific “last good” version, so I cannot point to a single exact version with full certainty.
