Chapter 14. Regression Tests

14.1. Introduction

The regression tests are a comprehensive set of tests for the SQL implementation in PostgreSQL. They test standard SQL operations as well as the extended capabilities of PostgreSQL. The test suite was originally developed by Jolly Chen and Andrew Yu, and was extensively revised and repackaged by Marc Fournier and Thomas Lockhart. From PostgreSQL 6.1 onward the regression tests are current for every official release.
