Hi,
The test case seems to have a problem: We cannot ensure that the SELECT happens after the pg_stat_activity can show the logical replication launcher. With the following patch the test will fail (without the patch it may happen very rarely): diff --git a/src/backend/replication/logical/launcher.c b/src/backend/replication/logical/launcher.c index 742d9ba68e9..1e155587c55 100644 --- a/src/backend/replication/logical/launcher.c +++ b/src/backend/replication/logical/launcher.c @@ -1162,6 +1162,7 @@ ApplyLauncherMain(Datum main_arg) * Establish connection to nailed catalogs (we only ever access * pg_subscription). */ + sleep(100); BackgroundWorkerInitializeConnection(NULL, NULL, 0); /* -- Regards, ChangAo Chen
