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?

Very good point. I have improved the text with the attached patch. I
also clarified the asynchronous case.

Patch applied thorough all current versions of the Postgres docs.
Thanks for the report.
