Jingyi Mei commented on MADLIB-1202:
------------------------------------

I also checked other scenarios when there are some other embedded caps:
 # when you specify top_values, there will be a column name with suffix __MISC__
 # when you set encode_nulls as True, there will be a column name with suffix 
__NULL 

I will address all of those 3 cases in one commit.

> encode_categorical_variables() creates all lower case column names for 
> boolean columns

> It would be handy if encode_categorical_variables() created lower case column 
> names for boolean columns vs upper case that require double quoting to query. 
> Current implementation generates "<boolean column name>_True" and "<boolean 
> column name>_False".
> Improvement to generate <boolean column name>_true and <boolean column 
> name>_false.
