-- pagc_normalize_address(addressString)
-- This takes an address string and parses it into address (internal/street)
-- street name, type, direction prefix and suffix, location, state and
-- zip code, depending on what can be found in the string.
-- This is a drop in replacement for packaged normalize_address
-- that uses the pagc address standardizer C library instead
-- USAGE: SELECT * FROM tiger.pagc_normalize_address('One Devonshire Place, PH 301, Boston, MA 02109');
SELECT tiger.SetSearchPathForInstall('tiger');
