PostgreSQL is an open-source object-relational database known for standards-focused SQL, ACID transactions, extensibility, and rich types such as JSONB, arrays, and ranges.
Use this playground to test PostgreSQL schemas, constraints, joins, CTEs, window functions, JSONB expressions, and other Postgres-specific SQL without configuring a server.
This page sends your script to a hosted, network-isolated PostgreSQL 18.4 runtime. Every Run executes the whole editor contents against a fresh database, then discards its database state and files. It does not run the database in your browser and it never connects to your own database.
Available output: HTML result tables, psql-style text, and CSV. The schema panel shows a bounded catalogue captured after successful execution. Large output may be truncated, and package installation, remote network access, persistent storage, and external database connections are not supported.
