Non-blocking PostgreSQL client for Node.js. Pure JavaScript and optional native libpq bindings.

This repo is a monorepo which contains the core [pg](https://github.com/brianc/node-postgres) module as well as a handful of related modules.

- [pg-cursor](https://github.com/brianc/node-postgres/tree/master/packages/pg-cursor)

Each package in this repo should have it's own readme more focused on how to develop/contribute. For overall documentation on the project and the related modules managed by this repo please see:

* Pure JavaScript client and native libpq bindings share _the same API_

* Connection pooling

* Extensible JS ↔ PostgreSQL data-type coercion

* Supported PostgreSQL features

* Parameterized queries

* Named statements with query plan caching

* Async notifications with `LISTEN/NOTIFY`

* Bulk import & export with `COPY TO/COPY FROM`

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](https://github.com/brianc/node-postgres/wiki/Extras).
