   MySQL: not allow `NaN`
   Postgres: allow `NaN` 
   official documentation states, `In order to allow numeric values to be 
sorted and used in tree-based indexes, PostgreSQL treats NaN values as equal, 
and greater than all non-NaN values.`
   
   Some similar issue with `-0.0` and `0.0` (This would also mess up the binary 
search/sorting)
