Hi, I tested the latest v11 patch series on the current master. Before applying the patches, I was able to reproduce the worker shortage scenario by running a parallel query that planned 2 workers but launched only 1 worker. The EXPLAIN ANALYZE output showed: Workers Planned: 2 Workers Launched: 1 I then applied: v11-0001-Add-a-guc-for-parallel-worker-logging.patch v11-0002-Implements-logging-for-parallel-worker-usage-in-util.patch v11-0003-Implements-logging-for-parallel-worker-usage-in-quer.patch The patches applied cleanly, but PostgreSQL failed to build.The build errors indicate that log_parallel_workers, log_parallel_workers_options, LOG_PARALLEL_WORKERS_NONE, and LogParallelWorkersIfNeeded() are referenced during compilation but could not be found, resulting in build failures in several files including execMain.c, vacuumparallel.c, nbtsort.c, brin.c, and gininsert.c. Because of the build failure, I was unable to proceed with runtime testing. Could you please clarify if there is any additional patch that needs to be applied, or if I may have missed any step while testing? Regards, Solai
