Migrate from 0.3.1 to 0.3.2

This table structure has been changed, from 3 tables (one for the asset, one for properties and one for data address) to a single table with json fields. To migrate an existing database, please first add the 3 new columns in the edc_asset table:

alter table edc_asset 
add column properties json default '{}',
add column private_properties json default '{}',
add column data_address json default '{}';

Then migrate the existing data in the new format:

update edc_asset set 
properties=(select json_object_agg(property_name, property_value) from edc_asset_property where asset_id_fk = edc_asset.asset_id and property_is_private = false),
private_properties=(select json_object_agg(property_name, property_value) from edc_asset_property where asset_id_fk = edc_asset.asset_id and property_is_private = true),
data_address=(select properties from edc_asset_dataaddress where asset_id_fk = edc_asset.asset_id);

After the migration, the tables edc_asset_dataaddress and edc_asset_property can be deleted.
