An Injection with Tree Awareness: Adding Staircase Join to PostgreSQL

Summary: Tree-aware staircase join injected into PostgreSQL for XPath over XML encoded with preorder/postorder ranks. Uses pre/post tree properties to support descendant/ancestor/preceding/following axes; shows speedups with small kernel changes and XPath semantics. (summarized by gpt-5-nano on Feb 09 2026)
