PostgreSQL server_version_num: connection refused

This error means kong is not able to talk to postgres.

Ty.
Yes but I don’t want database.
i see it’s possible to enable kong db-less.

KIC is installed in dbless mode by default.

For example with helm (version 3) you can run below to install kong in dbless mode.

helm upgrade -i my-kong kong/kong -n kong \
  --set ingressController.installCRDs=false \
  --create-namespace

How did you install Kong?
