> if a column is complex then the sub fields can't be referenced in cluster by, distributed
by, sort by clauses
> for example if column c1 is an object with attributes a and b then the following query
returns an error
> select * from t1 cluster by t1.c1.a (or similar queries)
> also the following query will return an error because current code doesn't distinguish
between a complex column or a table alias.
> select c1.a from t1
