While expanding it might be a worthwhile follow-up, it probably deserves its own dedicated discussion.
+1, listing output details is signing up for busywork.
Given how expansive and thorough our documentation is, and the fact this is user-facing output, I'm not seeing why this gets a pass on the documentation requirement. That said, I concur this patch needn't be responsible for dealing with that - I'm not even sure whether trying to do that on the vacuum/analyze pages is even the correct choice since at least some of what is output is object-specific and not generic to vacuum itself. Though stuff like timings are. Even if we want to leave ourselves the "it's undocumented so it can be changed at will" clause we can simply write that in.
maybe something along these lines:
"Prints detailed stats at <literal>INFO</literal> level for each table as it is processed."
I really don't like the word "Print" here. What the client decides to do with the INFO message is up to them - the interface to document for the server is simply sending the message and its details.
I was apparently mistaken about this info showing in the server log file though.
So that leaves me with suggesting:
"Enables the sending of a detailed INFO message to the client after each table is processed."
