Sounds good to me.

I think that's what I had initially, but it was changed somewhere along
the line.  It is a little more complicated for the versions that accept
column lists.

VACUUM ... ANALYZE [ [ table_name [ (column_name [, ...] ) ] ] [, ...] ]

ISTM that we need the extra brackets here to clarify that the table and
column list combination is what can be provided in a list.  Does that
make sense?  Or do you think we can omit the outermost brackets here?

Ah, yes.  That is a much better place.  I'll make this change.
