SQLSmith is a fuzz testing tool for PostgreSQL that automatically generates random SQL queries to uncover bugs in the query planner and executor. It is widely used by PostgreSQL developers and database vendors to stress-test SQL features and engine behavior under edge-case conditions. SQLSmith helps improve database robustness by revealing unexpected failures.

Features

  • Random SQL query generation for PostgreSQL
  • Stress-tests the query planner, parser, and executor
  • Helps identify crashes, assertion failures, and performance bugs
  • Supports different SQL constructs and PostgreSQL features
  • Highly configurable query complexity and structure
  • Used for regression testing in PostgreSQL development
