This fixes the simple HLint warnings, and adds a few suppressions to avoid noise.
The suppressions don't really solve the problems, but I think the warnings here are quite benign and I'm uncomfortable with how likely I would be to introduce a bug during refactoring.
In the case of _pg-client_ and _resource-pool_, we can't use the recommended functions anyway, and there doesn't seem to be a way to tell HLint to ignore entire packages.
I have updated the `make` targets to only fail if errors or warnings are found, not suggestions. This brings it in line with the CI job.
