Yeah, there's no support for repacking multiple tables in one command.
This is intentional. I think it'd be not very hard to add. But why?
People isn't likely to be running emergency VACUUM FULL on multiple
large tables in this way, listing multiple of them in a single command,
IMO anyway. So I think we don't need it.

(I think this is not similar to the case where normal vacuum is being
run in an emergency for XID wraparound purposes, which the ability to
run on multiple tables is more valuable. But at the same time, vacuumdb
does a much better job at that, since it can process multiple tables in
parallel.)
