pgcyan runs blue-green cutovers for PostgreSQL: it stands up your new instance, keeps it in sync, and switches over automatically — so you can upgrade major versions, resize storage, change SKUs, or move regions with no maintenance window. It even works when native upgrade tools are blocked by your extensions or configuration.
Bypass the limitations of native MVU tools. pgcyan orchestrates replication even when specific extensions or configurations typically block standard upgrade paths.
Stack your changes. Perform a Major Version Upgrade, shrink storage, and shift SKUs (e.g., to SSD v2) simultaneously in a single, coordinated window.
Shift across hardware generations or regions without the maintenance penalty. Maintain full availability while pgcyan handles the complex LSN synchronization.
Zero-downtime orchestration for mission-critical Postgres — currently in active development with a focus on Azure Database for PostgreSQL Flexible Server.
