From 5bb978b940a93c8f902aa4ea25ae39ef52eca3e3 Mon Sep 17 00:00:00 2001 From: "Chao Li (Evan)" Date: Thu, 2 Apr 2026 10:21:40 +0800 Subject: [PATCH v2 1/2] pg_test_timing: fix unit in backward-clock warning pg_test_timing measures timing differences in nanoseconds via INSTR_TIME_GET_NANOSEC(), but the backward-clock warning incorrectly reported the value as milliseconds. Fix the message to use "ns" so that it matches the actual unit of diff.
