@mothershipper I would like to work on this issue. Let me know how to onboard myself and I can start with it. Also, let me know where I should look for the code to be changed

These two functions iterate over a map to build a list, which we then display to the end user. Just need to sort the lists before passing it off to the survey library:

https://github.com/mothership/rds-auth-proxy/blob/main/cmd/proxy_client.go#L209
https://github.com/mothership/rds-auth-proxy/blob/main/cmd/proxy_client.go#L177

As far as onboarding for this project, I'd start by taking a look at the docker-compose file. It boots both the client and server proxy -- from there, you can use psql to connect to the client proxy. To test this feature in particular, it would help to build the binary locally make debug, and run the client proxy on your machine: rds-auth-proxy client.

You may need to copy the config file from configs/ into a config dir ~/.config/rds-auth-proxy/config.yaml. You'd probably need to duplicate a few of the entries in the "targets" and "upstream_proxies" block, same data, just different names, and remove the "default" targets if they exist.

@mothershipper thanks for the context. Is this repo a part of Hactoberfest 2021? If yes, I would like to give it a shot.
