Postgres Language Server: Enhancing Your Postgres Development Experience
The Postgres Language Server is a cutting-edge tool designed to improve Postgres development directly in your preferred code editor. Unlike some other SQL tools, this server focuses solely on Postgres, providing specialized support that acknowledges the unique and evolving nature of PostgreSQL syntax.
Features
Utilizing the Language Server Protocol (LSP), the Postgres Language Server seamlessly integrates into your code editor to offer a host of features that elevate coding efficiency and accuracy. These include:
- Linting: Automatic detection and correction suggestions for potential issues in your code.
- Hover Information: Instantly shows details about code elements when hovering over them.
- Type Checking: Verifies that your code uses data types correctly.
- Syntax Error Diagnostics: Identifies and helps fix syntax errors.
- Inlay Hints: Assists in understanding complex code by providing additional context within the editor.
- Auto-Completion: Speeds up coding by suggesting potential code completions.
- Code Actions: Executes commands like running a specific statement or an entire file at the click of a button.
- Formatter: Automatically organizes and formats your code for readability and consistency.
- More Features to Come: Future expansions will include comprehensive support for SQL and PL/pgSQL function bodies.
Why Postgres Language Server?
As Postgres continues to gain popularity, there's a noticeable gap in extensive support for PL/pgSQL across various IDEs and code editors. While some generic SQL language servers offer Postgres as a "flavor," they often lack the capability to fully understand the complex nature of Postgres.
The Postgres Language Server aims to bridge this gap by providing a specialized solution that leverages PostgreSQL's own parsing capabilities via libpg_query. This approach ensures that every valid Postgres query can be accurately interpreted, enhancing the developer experience by integrating easily into existing workflows.
Installation
Note: This server is currently in development and intended for collaborator use only. However, developers can join the ongoing development efforts by installing the server.
For Neovim Users:
- Add the
postgres_lspexecutable to your system's path. - Update your configuration by including the relevant settings to activate the server.
Building from Source:
Requirements: Nightly Cargo, Node, and npm installed on your system.
- Initialize the
libpg_querysubmodule with:git submodule update --init --recursive - For VS Code:
cargo xtask install - For other environments:
cargo xtask install --server - Ensure that
.cargo/binis included in your system's$PATH.
Using Github CodeSpaces:
If you're working on a Windows system, consider setting up your development environment in Github CodeSpaces, as Windows lacks support for libpg_query.
Initiate the environment setup and continue with the Rust installation and subsequent steps as described.
