Re: Function returning SETOF using plpythonu

Thanks :-)
That worked fine.

>plpy.execute returns dictionary, and you need a list. You may try this:

Then I tried to do some changes and try to return a SETOF type:
CREATE TYPE "test_python_t" AS (
name varchar(50)
);

CREATE FUNCTION "test_python_setof"()
RETURNS SETOF test_python_t AS '
records=plpy.execute("SELECT name FROM interface");
return [ (r["name"]) for r in records]
' LANGUAGE 'plpythonu';

And I'm getting ERROR: tuple return types are not supported yet.

On my production database server I'm using PostgreSQL 7.4 and using
language plpgsql I'm returning some SETOF type without problems.
Is this a feature that's missing on this version or I'm I doing
something wrong on code? If is a feature missing, is already implemented
on some version afterwards?
