PostgreSQL SQL Minifier
Free online PostgreSQL SQL minifier. Compress PostgreSQL queries into a single line, stripping whitespace and comments while preserving all syntax including dollar-quoted strings and operators.
What is PostgreSQL?
PostgreSQL (also known as Postgres) is a powerful, open-source object-relational database management system with over 35 years of active development. It is ACID-compliant, supports advanced data types including JSONB, arrays, and custom types, and provides robust support for complex queries, window functions, and CTEs.
PostgreSQL is the go-to database for applications that need reliability, data integrity, and advanced SQL features. It powers everything from small web applications to large data warehouses, and its extensibility makes it a popular base for specialized databases like TimescaleDB (time-series) and PostGIS (geospatial).
When formatting PostgreSQL SQL, using the PostgreSQL dialect ensures that Postgres-specific syntax — dollar-quoted strings, JSONB operators (->>, @>), ON CONFLICT, RETURNING, and LATERAL joins — is handled correctly and laid out clearly.
Frequently asked questions
Will minifying PostgreSQL SQL break dollar-quoted strings?
No. The PostgreSQL minifier correctly identifies dollar-quoted string boundaries (e.g. $$ or $tag$) and preserves their contents exactly, only removing whitespace outside of string literals and comments.
Does PostgreSQL minification strip comments?
Yes. Both single-line (--) and multi-line (/* */) comments are removed during minification. If you need to keep comments, use the SQL Formatter instead.
Are PostgreSQL-specific operators preserved when minifying?
Yes. JSONB operators (->, ->>, @>), text search operators (@@), and all other PostgreSQL-specific operators are preserved exactly as written — only whitespace between tokens is removed.
Why would I minify PostgreSQL SQL?
Minified SQL is useful when embedding queries in source code strings, passing SQL as URL parameters, reducing query log verbosity, or building SQL strings dynamically in application code where whitespace is irrelevant.
