Data import stuck at CREATE INDEX

My machine has been importing North America data for the past 16 days now, which to me seems unusually slow. The output currently shows:

...
CREATE INDEX
CREATE INDEX
CREATE INDEX

I checked what postgreSQL is doing by:

postgres=# select * from pg_stat_activity;
datid | datname  | procpid | usesysid | usename  | application_name | client_addr | client_hostname | client_port |         backend_start         |          xact_start           |          query_start          | waiting |          current_query
-------+----------+---------+----------+----------+------------------+-------------+-----------------+-------------+-------------------------------+-------------------------------+-------------------------------+---------+---------------------------------
12780 | postgres |   22028 |       10 | postgres | psql             |   |                 |          -1 | 2013-10-28 10:45:35.774566-07 | 2013-10-28 10:47:05.063072-07 | 2013-10-28 10:47:05.063072-07 | f       | select * from pg_stat_activity;
(1 row)

Does that mean the machine is still indexing data? When can I expect the importing to finish? Thanks!

EDIT: as one of the person answered below, I tried

nominatim=# \d place
                Table "public.place"
    Column    |          Type           | Modifiers

 osm_type     | character(1)            | not null
 osm_id       | bigint                  | not null
 class        | text                    | not null
 type         | text                    | not null

 admin_level  | integer                 |
 housenumber  | text                    |
 street       | text                    |
 addr_place   | text                    |

 country_code | character varying(2)    |
 extratags    | hstore                  |
 geometry     | geometry(Geometry,4326) | not null
Indexes:
    "idx_place_osm_unique" UNIQUE, btree (osm_id, osm_type, class, type)
    "place_id_idx" btree (osm_type, osm_id)
Triggers:
    place_before_delete BEFORE DELETE ON place FOR EACH ROW EXECUTE PROCEDURE pl
ace_delete()
    place_before_insert BEFORE INSERT ON place FOR EACH ROW EXECUTE PROCEDURE pl
ace_insert()

Does this mean my indexing is completed? If so, why does my pg_stat_activity still show recent timestamps?
