node-postgres is by design pretty light on abstractions. These are some handy modules we've been using over the years to complete the picture. The entire list can be found on our wiki.
node-postgres is free software. If you encounter a bug with the library please open an issue on the GitHub repo. If you have questions unanswered by the documentation please open an issue pointing out how the documentation was unclear & I will do my best to make it better!
When you open an issue please provide:
- version of Node
- version of Postgres
- smallest possible snippet of code to reproduce the problem
