Is that actually plpython, or plpgsql?  Because what you're showing is
not legal syntax in either bare SQL or plpython, but it would act as
you're reporting in plpgsql:

SELECT INTO in plpgsql is a completely different construct than SELECT
INTO in bare SQL: the INTO target is always a local variable of the
function.  You should use CREATE TABLE AS to get the effect you're
after.  This is covered in the docs page David pointed you to, as
well as in the plpgsql documentation.
