Returnera PostgreSQL UUID-array som lista med psycopg2

Det fungerar för mig utan att behöva analysera:

import psycopg2

query = """
    select array(select * from (values (1), (2)) s);
"""

conn = psycopg2.connect('dbname=cpn user=cpn')
cursor = conn.cursor()
cursor.execute(query)
rs = cursor.fetchall()

for l in rs:
    print l[0]

cursor.close()
conn.close()

Resultat när det körs:

$ python stackoverflow_select_array.py 
[1, 2]

Uppdatera

Du måste registrera uuid-typen:

import psycopg2, psycopg2.extras

query = """
    select array(
        select *
        from (values
            ('A0EEBC99-9C0B-4EF8-BB6D-6BB9BD380A11'::uuid),
            ('A0EEBC99-9C0B-4EF8-BB6D-6BB9BD380A11'::uuid)
        )s
    );
"""

psycopg2.extras.register_uuid()

conn = psycopg2.connect('dbname=cpn user=cpn')
cursor = conn.cursor()
cursor.execute(query)
rs = cursor.fetchall()

for l in rs:
    print l[0]

cursor.close()
conn.close()

Resultat:

$ python stackoverflow_select_array.py 
[UUID('a0eebc99-9c0b-4ef8-bb6d-6bb9bd380a11'), UUID('a0eebc99-9c0b-4ef8-bb6d-6bb9bd380a11')]
