Hi @NTS ,
unfortunately accessing a public database is one of the limitations we have today when using a Sincle EC2 (K3S) type cluster (see the limitations here). We should block any user to select “public” on a database when using a Single EC2 cluster.
We will support soon a port-forward option in our CLI to let you connect to any database, no matter their accessibility. In the meantime, you can ssh via our CLI to another application within your environment and connect to the PostgreSQL from there
