Since we might eventually have other 'concurrent commands', perhaps

CONCURRENT CREATE INDEX ...

would be best.

BTW, if we started to consider lazy vacuum a concurrent command we could
ditch the use of FULL, which is always confusing if you're talking about
database-wide vacuums. I know it'd take many versions to fully make that
change, but it seems worth it to me to reduce confusion. There's also an
issue of newbies thinking they should use vacuum full regularly because
it's somehow better than lazyvac.
