Is this part of an academic project or something? Frankly, it looks to
me like you need to acquire a lot of basic knowledge about how
postgresql works internally before you even start thinking about what
you are trying to do.

Serverside PLs can only be used in user-defined functions, and the
language used is specified in the function definition, as in

create function foo() returns text language mypl as $$ <code in mypl> $$;
