The SQL spec calls it a <table value constructor>. The VALUES clause
behaves like a SELECT that returns a fixed number of rows (1 or more)
whose columns contain the results of the specified expressions. The
v(ip) part is just a table and column alias (I omitted the optional AS
keyword out of long habit) to name the constructed table.
