PostgreSQL Extension Lifecycle & Version Upgrade Automation

This site helps PostgreSQL DBAs, platform engineers, Python DevOps builders, and database SREs treat PostgreSQL extensions as first-class infrastructure — tracking compatibility across major and minor versions, planning safe upgrade paths, and keeping production clusters predictable through every lifecycle phase.

You'll find tactical, copy-ready patterns for dependency resolution, compatibility matrices, CI/CD validation gates, and rollback automation built with Python and modern pipelines — engineered to survive partial failures and minimize downtime.

Everything here is geared toward compliance and audit readiness: deterministic catalog state, version-pinned manifests, and reproducible recovery workflows you can wire straight into your platform.

Architecture & Lifecycle Foundations: catalog synchronization, dependency resolution, security boundaries, version control, and rollback design. Upgrade Planning Compatibility matrices, async upgrade simulation, error categorization, downtime thresholds, and test routing. Execution & Rollback ALTER EXTENSION automation, snapshot & point-in-time recovery, and resilient rollback workflows.

What you'll find here

Content is organized into three pillars, each drilling from architectural fundamentals down to hands-on, production-grade implementation guides.
