I'm in the process of migrating from an RDS pg14 instance to pg15.3. As part of the migration process, the application code makes a test connection to the new instance. This failed. I tried manually connecting to the kube pod where the test query was submitted from, and from there was able to manually connect to the new instance (using psql) just fine.

In case it's relevant, the application code is running on nodejs v18.14.2 using pg 8.11.0.
