I really like the sql() helpers and the naming of the unsafe() method. The file query helper is great - I've moved to using external query files for everything in a current project.

I've used pg-promise a lot and this seems to cover a good bit of the core functionality and could be extended pretty well in a project. Do you plan to continue building out features or are you looking to keep this as lean as possible long term?

Also, does sql.file() support named parameters or just indexed parameters (like $1)?
