Perhaps it may be confusing, but at the same time, it's educational  
to put VALUES at the top level. Having not read the SQL spec in  
detail, I do rely on the Postgres documentation as a quick reference.  
Thanks to the high-level of SQL-spec compliance, the Postgres  
documentation is pretty helpful in that way. And I'm always  
pleasantly surprised when I learn something new just from looking  
indices such as this.
