+1 for SQL 2011. I downloaded the standard but I couldn't find any section 
dedicated to, In postgres doc, though, they are stating that they are not 
following the standard strictly: 
https://www.postgresql.org/docs/11/sql-keywords-appendix.html. Shall we follow 
that list and follow the standard as it is mentioned there?

thanks @maropu for starting it!

> Which SQL standard does Spark SQL follow (e.g., 2011 or 2016)?
I think SQL 2011 is good, but if we can't find a public version, maybe it's 
also OK to follow 
[postgres](https://github.com/postgres/postgres/blob/ee2b37ae044f34851baba69e9ba737077326414e/src/backend/parser/gram.y#L15366)

> Where should we hanlde reserved key words?
I think it should be `SqlBase.g4`, but a problem is, the g4 files defines 
`non-reserved` keywords, not `reserved` ones. Maybe we need to update it.

> Where should we docment the list of reserved/non-reserved key words?
I think the new files you created in this PR is a good place to document it
