Four projects, one maintainer
Pick the one that matches the problem you have this quarter
Four tools, each solving one operational problem, all maintained upstream by the same person. Every project page below covers what the tool does, what is being worked on right now, and what funding its maintenance buys you.
Each page covers the tool, its current backlog, and its maintenance funding
Migrate to PostgreSQL from any source
pgloader handles heterogeneous database migrations (MySQL, SQLite, and more) with automatic schema conversion and high-performance loading. Designed for real-world edge cases, it has been maintained and used in production since 2005.
Copy and upgrade PostgreSQL databases
pgcopydb enables PostgreSQL-to-PostgreSQL copy, upgrade, and migration workflows with minimal downtime. It is designed for modern environments where source and target systems are not binary-compatible or run on separate platforms/clouds, making WAL-based replication impractical. Built on logical decoding, it provides a reliable, repeatable approach to controlled data movement.
Automated PostgreSQL high availability
pg_auto_failover monitors PostgreSQL nodes and manages failover automatically using native PostgreSQL features. It provides a clear, predictable high availability model without complex external orchestration.
PostgreSQL extension whitelisting
pgextwlist lets cloud providers and hosting platforms safely offer PostgreSQL extension installation to non-superuser tenants. It intercepts CREATE EXTENSION statements and runs whitelisted ones under superuser privileges, dropping those privileges before returning control — a sudo model for extensions. Used in production by Heroku, Aiven, Zalando, and Azure Database for PostgreSQL.
Professional upstream maintenance
These projects are actively maintained with a paid support model that ensures ongoing fixes, compatibility with new PostgreSQL releases, and regular improvements.
