[Psycopg] INET type and arrays: too much casting?

[Stephane Bortzmeyer]

If I create a table:

CREATE TABLE Foobar (addr INET);

psycopg2 can write data just fine:

>>> cursor.execute("""INSERT INTO Foobar VALUES (%s)""", ["2001::1"])
>>> 

But if the column has an array type:

CREATE TABLE Foobar (addr INET[]);

psycopg2 can no longer insert data:

>>> cursor.execute("""INSERT INTO Foobar VALUES (%s)""", [["2001::1", "2001:db8::dead:babe"]])
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
psycopg2.ProgrammingError: column "addr" is of type inet[] but expression is of type text[]
HINT:  You will need to rewrite or cast the expression.
