[robe]

Example:

SELECt (addy[1]).address, (addy[1]).predirabbrev, (addy[1]).streetname   from reverse_geocode('POINT(-87.6294 41.8885)'::geometry);

Outputs:

address | predirabbrev | streetname
--------+--------------+------------
    333 |              | Dearborn

Instead of

address | predirabbrev | streetname
--------+--------------+------------
    333 | N            | Dearborn
