---- ADMIN1 Geometry Table -----

-- for countries that have admin1 regions we use data from qs_adm1_region
--------------------------------------------------------------
--- add column global_id to admin1 and admin1 region tables
--- only do this if they don't exist:
--ALTER TABLE qs_adm1 ADD COLUMN global_id INT;
--ALTER TABLE qs_adm1_region ADD COLUMN global_id INT;
--- create a unique id for both the adm1 and adm1_region tables
--- first create new table in memory
--- use the cartodb_id with the table name
