    1. Please add unit tests for temp tables as well in `TestCTTAS` class.
    2. Should we consider similar functionality for views?

>          Components: SQL Parser
>    Affects Versions: 1.11.0
>            Reporter: Prasad Nagaraj Subramanya
>            Assignee: Prasad Nagaraj Subramanya
>             Fix For: Future

>
> Currently, if a table/view with the same name exists CREATE TABLE fails with 
> VALIDATION ERROR
> Having "IF NOT EXISTS" support for CREATE TABLE will ensure that query 
> succeeds
