When you add a Database Endpoint to a PostgreSQL Database, Aptible automatically performs periodic TCP health checks to ensure the Endpoint can reach the Database.

These health checks consist of opening a TCP connection to the Database and closing it once that succeeds. As a result, PostgreSQL will log a incomplete startup packet error message every time the Endpoint performs a health check.


If you have a Database Endpoint associated with your PostgreSQL Database, you can safely ignore these messages. You might want to consider adding filtering rules in your logging provider to drop the messages entirely.
