You can use the catalogs:

SELECT t.tgname, t.tgrelid::regclass, t.tgfoid::regprocedure as 
function_name, pg_get_functiondef(t.tgfoid) as function_body FROM 
pg_trigger t WHERE NOT tgisinternal;

There is additional information in the table such as when the trigger 
fire, etc.
Have a look at: 
https://www.postgresql.org/docs/12/catalog-pg-trigger.html

Another way is querying the information schema:

SELECT * FROM information_schema.triggers;

https://www.postgresql.org/docs/12/infoschema-triggers.html
However you won't get there the function body.
