Ok this is strange. Shouldn't it always be one or the other? Total row count for the table is 279,096. 

doggies=# select count(*) from data where features_bin is null;
 count
--------
 279096
(1 row)

doggies=# select count(*) from data where features_bin is not null;
 count
--------
 279096
(1 row)
