From c9e38a569c5fe8006a08f63ba6b63d8021704c53 Mon Sep 17 00:00:00 2001 From: Michael Paquier Date: Fri, 31 Oct 2025 11:24:24 +0900 Subject: [PATCH] Add test tracking WAL receiver shutdown for primary_conninfo updates The test introduced by this commit checks that a reload of primary_conninfo leads to a WAL receiver restarted, by looking at the request generated in the server logs. This is something for what there was no coverage. This has come up for a different patch, while discussing a regression where a WAL receiver should not be stopped while waiting for a new position to stream, like at the end of a timeline. In the case of the other patch, we want to check that this log entry is not generated, but if the error message is reworded the test would become silently broken. The test of this commit ensures that we at least keep track the log message format, for a supported scenario. Extracted from a larger patch by the same author.
