Establishing the PostgreSQL standard: What's Postgres compatible?
What does it mean to be "PostgreSQL compatible"? This half-day session invites Postgres developers, contributors, and community members to define a practical framework of criteria and tests for PostgreSQL compatibility.
About
We'll focus on designing a test harness using existing regression tests and propose new tests covering core features, build behaviour, Application Binary Interface (ABI) stability, WAL-based backup and replication, and other key areas identified during the session. The goal is to outline a concrete path towards meaningful compatibility certification.
This will be a focused, technical working session. After a brief overview of the current landscape, participants will split into small groups, with discussion leads for each topic, to identify compatibility concerns and propose test approaches. Interest areas include:
- Core feature set behaviour
- Build and smoke test coverage
- ABI stability
- Backup and replication behaviour (WAL, PITR, streaming, logical)
We aim to close the session with a preliminary outline of criteria for meaningful compatibility testing and a roadmap for continued collaboration.
