Stop dangerous Postgres migrations before hitting production

1 follower

pgfence is a source-available CLI that catches dangerous Postgres migrations in your CI/CD pipeline. Unlike existing tools in Ruby or Go, it is natively built for the Node.js ecosystem (Prisma, TypeORM, Drizzle, Sequelize). It analyzes DDL to predict precise locking behaviors (like ACCESS EXCLUSIVE), flags risks, and generates the exact zero-downtime rewrite recipes you need. Stop shipping DB downtime masked as harmless schema changes.
