Of course having the ability to execute arbitrary plpgsql in .sql
scripts would be handy in some cases as well, though as others pointed
out there are alternatives.
I don't know if it's possible. PL/pgSQL parser live in different context
than SQL parser and PostgreSQL supports more languages than one. These needs
different syntax, maybe:
EXECUTE CODE (integer, integer) RETURNS integer AS $$
DECLARE c integer = 10;
BEGIN
RETURN $1 + $2 + c;
END;
$$ LANGUAGE plppgsql USING(10,20);
we can use plplgsql compiler, and only use different memory context. It's
maybe better solution than temp functions.
