pg-query-formatter

Lightweight query string formatter for PostgreSQL in Node.js (v0.0.5, last updated 2014). Provides a printf-like syntax for safely building SQL queries with escaping for identifiers, literals, and subqueries. Supports parameterized queries via toParam() for use with node-postgres. Currently in maintenance mode; no updates since 2014. Alternative libraries like pg-promise, squel, or knex may be more actively maintained.
