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?
