Dear Amit, Vingesh, Thanks for giving comments!

Previously I avoided coding like yours, because there is a room that converted node can connect to another publisher. But per off-list discussion, we can skip it by setting max_logical_replication_workers = 0. I refactored with the approach. Note that the GUC is checked at verification phase, so an attribute is added to start_standby_server() to select the workload. Most of comments by Vignesh were invalidated due to the code change, but I hoped I checked your comments were not reproduced. Also, 0001 was created to remove an unused attribute. > Shouldn't this be an open item for PG17? Added this thread to wikipage. Best Regards, Hayato Kuroda FUJITSU LIMITED https://www.fujitsu.com/
