What It Is
Imagine a smart spell-checker and grammar assistant specifically for your SQL code, but for Postgres. This project provides a Language Server Protocol (LSP) implementation that understands Postgres SQL syntax, allowing various development tools to offer features like real-time autocompletion, error checking, and code formatting.
It solves the problem of writing error-prone SQL by providing instant feedback, consistent code formatting, and migration linting, directly integrating into popular editors like VSCode and Neovim. This makes Postgres development faster, more reliable, and reduces the time spent debugging syntax errors.
License Verdict
MIT License — Build and Sell Freely — Commercial Use Approved • No Copyleft Restrictions
The MIT license is highly permissive. You can use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the software. This includes using it in proprietary software and for commercial purposes without needing to open-source your own code.
How to Use It
The project can be quickly set up using Docker Compose for local development. It provides a server-client architecture, and you'll typically integrate its capabilities via an editor extension or CLI for immediate use.
Prerequisites:
- Docker
- Docker Compose
Estimated setup time: 10 minutes.
docker-compose up -dWhat I'd Build With This
SQL Linting and Formatting as a Service (micro-saas)
Build a simple web service where users can paste Postgres SQL queries or upload `.sql` files to get instant linting, formatting, and syntax diagnostics. Offer API access for programmatic checks. Indie developers and small teams who need quick SQL validation would pay for this.
Effort: 1 Week Build Time · Target: Indie Developers & Small Teams · Pricing: $19/mo (basic) - $49/mo (API access)
Cloud-Native Postgres IDE (saas)
Develop a cloud-based IDE specifically tailored for Postgres development. Integrate all LSP features like autocompletion, type checking, formatting, and migration linting directly in the browser. Connect it with popular cloud database providers for seamless workflow. Development teams and data engineers would subscribe for enhanced productivity.
Effort: 3 Months Build Time · Target: Dev Teams & Data Engineers · Pricing: $99/user/month
Automated Database Migration Validation Platform (enterprise)
Create a bespoke platform or CI/CD plugin for large enterprises that automatically lints and validates Postgres schema migrations before deployment. This ensures compliance with internal standards, prevents common errors, and enforces best practices across large, complex database infrastructures. Large organizations with strict change management would pay for this specialized tooling.
Effort: 6 Months Build Time · Target: Large Enterprises · Pricing: $5,000 - $20,000/month (license + support)
Sai Pavan Gopularam's Take
This LSP for Postgres is a foundational piece of tech. It's like having a dedicated Postgres expert checking your code in real-time, which is huge for developer productivity. I'd lean into building a cloud-based SQL formatter and linter, charging teams around $50/month for a premium tier.
Watch Out For
- Dependency on `libpg_query`: The project relies on `libpg_query` for Postgres' own parser. While this ensures 100% syntax compatibility, updates to Postgres syntax might require updates to `libpg_query` first, potentially causing slight delays in support for bleeding-edge features.
- Editor Integration Effort: While the core LSP is robust, integrating it fully into less common or custom editors might require significant effort to develop or maintain editor-specific plugins, as the project primarily provides the language server, not the editor front-end.
- Performance with Large Schemas: For extremely large and complex Postgres schemas, the real-time analysis features like autocompletion or type checking might introduce noticeable latency, depending on the underlying hardware, database connection, and network conditions.
