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.
