This looks good to me. I didn't know Postgres natively supported IP address types, but it makes sense to map them to the same type that hasql uses. I guess this means we should bump the lower bound on our hasql dependency to 1.6.1.2 because it looks like that's when support for this was added to hasql.

Yep, that sounds good to me. @JonathanLorimer if you could change that lower bound, we'll get this merged. Thanks for your contribution!

As a side note, I was wondering if you have a public nix cache. I am trying to set up my dev environment to test, but haskell.nix is trying to rebuild the world!

You should be able to cachix use rel8

You should be able to cachix use rel8

unfortunately I get this when I run cachix use rel8: Binary cache rel8 doesn't exist or it's private and you don't have access it

but I just did nix-shell -p ghc cabal-install postgresql ghcid and I got things working

@shane-circuithub or @ocharles can you approve the workflow? Tests are passing locally.
