Обсуждение: Synchronous Multimaster Replication
The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/11/different-replication-solutions.html Description: Not sure if this is an error but I was wondering about this sentence: "In fact, write performance is often worse than that of a single server". Isn't syncronous multimaster write performance always (rather than "often") worse than that of a single (non-distributed) server?

I have improved the text with the attached patch. I also clarified the asynchronous case. -- Bruce Momjian <bruce@momjian.us> http://momjian.us EnterpriseDB http://enterprisedb.com + As you are, so once was I.
