PostgreSQL Formatter

The PostgreSQL Formatter reformats PostgreSQL SQL scripts to a consistent style across teams. It targets DBAs, backend developers, and data engineers who maintain migrations, stored procedures, and test queries. The tool accepts raw SQL text and outputs a consistently styled version that enforces a defined standard for keyword casing, indentation, line breaks, and alignment, while preserving semantics. This improves readability, reviewability, and maintainability, enabling faster code reviews and cleaner diffs in version control.
Conceptually, the tool uses a formatting pipeline: it tokenizes the input, applies a style engine according to the selected options, reflows long lines, and reconstructs the SQL string. It supports both simple and advanced styles, such as uppercase keywords, aligned columns in SELECT lists, fixed indentation, and optional per-project templates. The output is a plain SQL string suitable for editors, CI pipelines, or documentation. It does not execute queries or validate runtime results.
Audience benefits include reduced review time, consistent codebases, and easier onboarding for new contributors. Unique value lies in its focus on PostgreSQL idioms (WITH clauses, CTEs, CREATE or ALTER statements) and its ability to export a ready-to-paste block. Use cases include standardizing migration scripts, formatting ad hoc queries, and enforcing team standards across multiple repositories; it complements linters and IDE tooling.
