Wiki / Versions

Parallel JOIN, aggregate

Recorded source states and original language descriptions. Missing version evidence stays unknown.

The source snapshot records transitions for PostgreSQL 8.1–18. The historical matrix records independent cells for 7.4–18. Neither records support for PostgreSQL 19 or 20; newer versions remain unknown. These source claims are distinct from runtime measurements.
