i have table, region, defined

 place_id     | integer    |   pts          | point[]    |   region_name  | text       |   region_id    | integer    | not null default nextval('region_region_id_seq'::regclass) 

and insert row python. have array pgon

place_id = 6, name = "american samoa" python command line is:

cur.execute("insert region (place_id,pts,region_name) values (%,%,%)",(place_id, pgon, name)) 

but valueerror: "unsupported format character ',' (0x2c) @ index 55"

i have done inserts before, not point[] in target. can tell me how should doing this? thanks.

create table t (p point[]);
