> Create table statements can have two forms as follows.
> * CTAS: create table t as select ...
> * Simple statement: create table t (int4 id, ...
> In the logical plan, CTAS node must have a child while simple CreateTable
> node must not. However, the same CreateTableNode structure are used for both
> statements, thereby making confusing and potential bugs.
