Incorrect Contact Reference option for Postal Code in civicrm_data.sql
Copy-error in the sql-file civicrm_data for new databases :
In line (5178): (@option_group_id_acConRef, 'Postal Code' , 8, 'country'
The name for this contact_reference_options (in the table option_values) is 'country', but I think it must be 'postal_code'.
