Did you get a fix for this?
hello there am also facing this kind of issue.
following is the log of pre-migration pod.
i am using postgresql from Azure and version is 13
That particular error looks like Can not connect to PostgreSQL DB requiring TLS > 1.0 · Issue #6645 · Kong/kong · GitHub and should have been cleared by the luasec upgrade in 2.4. If you’re seeing it on a later version, I’d recommend submitting a new Kong/kong issue, including any information you have about the Postgres server’s TLS configuration or TLS-related overrides you’ve set in the Kong configuration.
