Since PostgreSQL 10, the integer_datetimes configuration parameter has been fixed at true, yet client connections continue to receive it in the startup message. This reflects a historical shift in how the server represents temporal data, moving away from floating-point datetime implementations. The announcement highlights that this GUC is effectively a no-op for modern deployments while remaining part of the protocol handshake.

• The integer_datetimes GUC has been hardcoded to true since PostgreSQL 10
• Client libraries still receive this parameter during connection startup
• No action required for modern PostgreSQL 10+ deployments
• This GUC is a historical artifact with no functional impact today
