check This method needs address_standardizer extension.

Examples

Using address_standardizer_data_us extension

CREATE EXTENSION address_standardizer_data_us; -- only needs to be done once

Variant 1: Single line address. This doesn’t work well with non-US addresses

SELECT house_num, name, suftype, city, country, state, unit  FROM standardize_address('us_lex',
               'us_gaz', 'us_rules', 'One Devonshire Place, PH 301, Boston, MA 02109');

house_num |    name    | suftype |  city  | country |     state     |      unit
----------+------------+---------+--------+---------+---------------+-----------------
1         | DEVONSHIRE | PLACE   | BOSTON | USA     | MASSACHUSETTS | # PENTHOUSE 301

Using tables packaged with tiger geocoder. This example only works if you installed postgis_tiger_geocoder.

SELECT *  FROM standardize_address('tiger.pagc_lex',
         'tiger.pagc_gaz', 'tiger.pagc_rules', 'One Devonshire Place, PH 301, Boston, MA 02109-1234');

Make easier to read we’ll dump output using hstore extension CREATE EXTENSION hstore; you need to install

SELECT (each(hstore(p))).*
 FROM standardize_address('tiger.pagc_lex', 'tiger.pagc_gaz',
   'tiger.pagc_rules', 'One Devonshire Place, PH 301, Boston, MA 02109') As p;

    key     |      value
------------+-----------------
