From 882bdcf9fd05f50153bc974568e48add76547fd3 Mon Sep 17 00:00:00 2001 From: Michael Paquier Date: Mon, 23 Mar 2026 18:14:28 +0900 Subject: [PATCH] Fix invalid value of pg_aios.pid, function pg_get_aios() When the value of pg_aios.pid is found to be 0, the function had the idea to set "nulls" to "false" instead of "true", without setting the value stored in the tuplestore. This could lead to the display of buggy data. The intention of the code is clearly to display NULL when a PID of 0 is found, and this commit adjusts the logic to do so. Issue introduced by 60f566b4f243.
