Hi all,
is there a way to define functions and/or triggers in a function?
For example, can I create a function that takes an argument and defines a
function that has the name passed as argument to the first function?
Something like this .....
CREATE FUNCTION test (name varchar) RETURNS VOID AS $$
BEGIN
CREATE FUNCTION name ( ) (here "name" should be expanded to the
variable content) RETURNS ....
...
END
$$
Is there a way to do this? Thanks

Yes, it's possible. Use EXECUTE.
There is one example under "Example 38-9. Porting a Procedure from
PL/SQL to PL/pgSQL"
http://www.postgresql.org/docs/8.4/static/plpgsql-porting.html
Also have look in:
http://www.postgresql.org/docs/8.2/static/plpgsql-statements.html
under "37.6.5. Executing Dynamic Commands"
