The **pgsql‑parser** monorepo provides Node.js tools for working with PostgreSQL SQL at the abstract‑syntax‑tree (AST) level. It bundles a WebAssembly‑based wrapper around the real PostgreSQL C parser (for parsing SQL into an AST and back), a pure‑TS deparser, utilities for type‑safe AST construction, traversal, version‑transformation, and a CLI, making it useful for developers building database tooling, query analysers, or code‑generators that need reliable, version‑aware PostgreSQL parsing and manipulation.
