Machinepack PostgreSQL

Structured Node.js bindings for connecting to and running queries against a PostgreSQL database. Version 4.0.2 is the latest stable release. It is part of the Sails.js ecosystem and implements the Waterline Driver Interface. Release cadence is irregular; primarily maintained for legacy Sails applications. Key differentiators: uses machine definitions for structured operations, integrates with Sails' Waterline ORM, wraps the `pg` driver. Unmaintained since 2017; prefer `pg` directly or newer Waterline adapters.
