Problem with "-f implies -n" approach is, it breaks backward

tables. For example the particular user wants to use the standard
pgbench tables and is not satisfied with the built in scenario. I know
at least one user does this way.

If we care enough about that case to attempt the vacuum anyway then we need to do something about the error message; either squelch it or check for the existence of the tables before attempting to vacuum. Since there's no way to squelch in the server logfile, I think checking for the table is the right answer.
