upgrade badger to v4

Upgrade badger to v4
Upgrade go to 1.19

This all looks good to me. I think the checks are just failing because the workflow is pointing at an older go version which can't build this version.

So you can either bump the go version in the workflow to the latest go (1.20.2) or I can grab your changes and move it in myself.

Thanks,

Actually, I'm getting test failures when running the tests on my machine, are you also seeing this?

badgerholdv4$ go test
store_test.go:158:

        exp: &errors.errorString{s:"unexpected EOF"}

        got: <nil>
