Introducing pgroll: zero-downtime, reversible, schema migrations for Postgres

Schema migrations in databases can be challenging due to potential breaking changes, multiple intricate steps, unexpected locks, and difficult rollbacks. To address these issues, Xata has developed pgroll, an open-source tool for Postgres databases that simplifies schema migrations by allowing users to define them in a high-level JSON format, enabling instant rollbacks, zero downtime, and automated backfills.
