Hello PL/Python

Today afternoon I a little study libpython1.5 and I mean create
new PL language is not a problem.

I a little play with it, and here is effect:

test=# CREATE FUNCTION py_test() RETURNS text AS '
test'# a = ''Hello '';
test'# b = ''PL/Python'';
test'# plpython.retval( a + b );
test'# ' LANGUAGE 'plpython';
CREATE
test=#
test=#
test=# SELECT py_test();
py_test

PS. I'am not Python guru, I love 'C' and good shared libs only :-)
