RegreSQL Guard is a SaaS platform that provides automated regression testing for PostgreSQL databases. Inspired by the “RegreSQL: Regression Testing for PostgreSQL Queries” article, this service addresses the critical need for data integrity and reliability in applications that rely on PostgreSQL. It allows developers and database administrators to easily set up, run, and monitor tests that ensure existing query functionality remains intact after code changes or database updates. The platform integrates with CI/CD pipelines, offering alerts and detailed reports on any regressions found, thereby preventing costly data errors and downtime.
