The Postgres Language Server is a toolchain for Postgres development, built on Postgres' own parser libpg_query, providing features such as autocompletion, syntax diagnostics, and formatting. It is designed to work standalone, without connecting to a database, but will have optional features that require a database connection. The project aims to make Postgres tooling more accessible and to build missing features. It supports various editors, including VSCode, Neovim, and Sublime Text.
