Well building a suitable replacement for VACUUM FULL is more work than I was
proposing. The no-op ALTER TABLE rebuild still has the disadvantage of
requiring 2x the space taken by the table (and potentially more if you have
large indexes).

I also think it's a safer course of action to create a new command, spend one
or two releases improving it until we're sure it meets everyone's needs, then
drop the old command.
