    Description
    The purpose of this module is to implement "sparse" fields, i.e., fields
that are mostly null. This implementation circumvents the PostgreSQL
limitation on the number of columns in a table. The values of all sparse
fields are stored in a "serialized" field in the form of a JSON mapping.
