Allow multiple tables to be specified in one VACUUM or ANALYZE command.

Browse Source 
Not much to say about this; does what it says on the tin.

However, formerly, if there was a column list then the ANALYZE action was
implied; now it must be specified, or you get an error.  This is because
it would otherwise be a bit unclear what the user meant if some tables
have column lists and some don't.

editorialization by me
