thanks Adrian, exactly what I was missing :-)
about knowing if I should...
We have to create a set of triggers (insert, update, delete) within a
huge set of tables. and that list of tables, and structure of them can
be customized, maintained, ...
so we were looking for a standard script to automatize the building of
the whole thing, taking list of columns and constraints (for PK)
directly from pg_catalog.
Now it works :-)
but.. why do you ask that question ? is there any king of hidden wolf we
didnt see ?
See David Johnston's answer. Nested quoting will drive you to drink(or

Sure you can:
CREATE OR REPLACE FUNCTION public.test_fnc()
RETURNS void
LANGUAGE plpgsql
AS $function$
DECLARE
bidule text;
BEGIN
bidule:='myfunc';
EXECUTE 'create function ' || bidule || '() RETURNS void language
plpgsql AS $fnc$ BEGIN END; $fnc$ ';
END;
$function$
select test_fnc();
test_fnc
----------
\df myfunc
List of functions
Schema | Name | Result data type | Argument data types | Type
--------+--------+------------------+---------------------+------
public | myfunc | void | | func
Whether you should is another question.
