Hello,
I need to generate some procedures that depend data models stored in my DBs.
As I have different models in different databases, the stored procedures will differ.
As I have different models in different databases, the stored procedures will differ.
My idea is to generate the required stored procedures dynamically once a model is defined.
I will probably do this within the application. But is there a way to achieve this with plpgsql ?

here a naive try to illustrate my idea:
CREATE OR REPLACE FUNCTION test(p1 int)
RETURNS integer AS
$BODY$
RETURNS integer AS
$BODY$
EXECUTE'
CREATE OR REPLACE FUNCTION generated(p2 int)
RETURNS integer AS
$BODY$
BEGIN
return p2 + ' || p1 || ';
END;
$BODY$
LANGUAGE ''plpgsql'' VOLATILE
';
RETURNS integer AS
$BODY$
BEGIN
return p2 + ' || p1 || ';
END;
$BODY$
LANGUAGE ''plpgsql'' VOLATILE
';
ERROR: syntax error at or near "BEGIN"
SQL state: 42601
Character: 156
