[~smilegator] by the way, I just checked and there is a (minor) difference: 
when you use `range()` and define it as a sub-query called `x`, for instance, 
the default name for the column became `x.id`, instead of just `x`, that is the 
behaviour in Postgres. For instance:

{code:sql}
from range(-32766, -32764) x;
{code}
In Spark, looks like you should reference to these values as `x.id`. Meanwhile, 
in Postgres you can call them through just `x`.

This is similar to what Spark provides: range. 


{code:java}
SELECT * FROM generate_series(1,3)
{code}
can be rewritten to 
{code:java}
SELECT * FROM range(1,4)
{code}
