Call plpgsql Function from a PL/Python Function in PostgreSQL
Is is possible to call a plpgsql function
(or any PostgreSQL function
) from a PL/Python
function?
So, something like this:
CREATE FUNCTION somefunc() RETURNS void AS $$
DECLARE
...
BEGIN
...
END;
$$ LANGUAGE plpgsql;
And then use it here
CREATE FUNCTION pythonFunc() RETURNS void AS $$
...
someFunc() #postgreSQL function
...
$$ LANGUAGE plpythonu;
python postgresql plpython

create function plpython_function()
returns void as $$
plpy.execute('select plpgsql_function()')
$$ language plpythonu;
PL/Python Database Access
How would you pass arguments on from the plpython_function to the plpgsql_function? The short answer to this would be, "import plpy and use plpy.quote_literal". My reply to that would be, "that's all very well, but 8.2 (actually, Greenplum) does not have plpy.quote_literal, it is actually quote_literal that I want to call!" Bootstrap problem.
