pgsql: Handle domains over arrays like plain arrays in PL/python.

Handle domains over arrays like plain arrays in PL/python.

Domains over arrays are now converted to/from python lists when passed as
arguments or return values. Like regular arrays.

This has some potential to break applications that rely on the old behavior
that they are passed as strings, but in practice there probably aren't many
such applications out there.
