From 0beda36f7daab693d243a344b87c0c1362cbf535 Mon Sep 17 00:00:00 2001 From: "Paul A. Jungwirth" Date: Thu, 3 Sep 2026 12:55:21 -0700 Subject: [PATCH v1] Document the privileges FOR PORTION OF needs on the range column Since UPDATE FOR PORTION OF implicitly updates the application-time column, and since UPDATE/DELETE FOR PORTION OF implicitly reads it, we should mention that UPDATE and/or SELECT permissions are needed for that column when doing an UPDATE/DELETE.
