I'm trying to connect postgreSQL instance in cloud SQL to my pgAdmin. And I'm totally confused. How can i do that?
When you are creating your postgres instance you have to allow access to the ip address from the postgres' client is running.
Now to verify the connectivity from the client to Cloud SQL instance I recommend you to do it the first time with the command line console.
psql -h [postgres instance ip address] -u postgres
.
You can follow the official documentation for “Connecting psql Client Using Public IP” in the link.
