    Convert all incoming protocol numbers to string

    PostgreSQL is more sensitive for types than MySQL when it selects
    something from columns in database. So it fails when it tries to
    select from string field comparing with integer value.

    Added unit test to verify conversion of protocol numbers to
    strings.
