Yes.  And there is a bigger issue here, which is that the output of
VACUUM VERBOSE is meant to be sent to the client for *human* readability.
(As you noted, INFO-level messages don't normally go to the server log
in the first place, and that's not by accident.)  Repeating the full table
name in every line will be really annoying for that primary use-case.
I am not sure what we want to do to address Masahiko-san's use-case, but
ideally his workflow wouldn't involve log-scraping at all.  It definitely
shouldn't involve depending on INFO messages --- for one thing, what
happens when those get translated?
