Master baker tier. Every paragraph earns its place on the tray.
Summary
RegreSQL is a tool that brings PostgreSQL's regression testing methodology to application SQL queries, helping developers catch both correctness bugs and performance regressions before deployment. The article addresses the common problem of production SQL issues and the practice gap in systematic SQL query testing, positioning RegreSQL as a solution to prevent deploying broken or slow queries through automated testing with performance baselines.

· 5 pulledRegreSQL brings PostgreSQL's regression testing methodology to your application queries, catching both correctness bugs and performance regressions before production.
As puzzling as it might seem, the common problem with production changes is the ever-present 'AHA' moment when things start slowing down or crashing straight away.
Testing isn't easy as it is, but there's a widespread practice gap when it comes to testing SQL queries.
Some might pretend to 'fix it' by using ORMs to abstract away the problem. Others treat SQL as 'just glue code' that doesn't deserve systematic testing.
Stop deploying broken SQL queries. RegreSQL provides regression testing for PostgreSQL queries with performance baselines and automated warnings.
