How to get the trigger(s) associated with a view or a table in PostgreSQL

Question

I have one requirement that I have to get the list of triggers associated to the given table/view.
Can anyone help me to find the triggers for a table in PostgreSQL?

Answer 1

The problem with the view information_schema.triggers (besides being slow) is, per documentation:

The view triggers contains all triggers defined in the current database on tables and views that the current user owns or has some privilege other than SELECT on.

Meaning, you only get to see triggers you have appropriate privileges on.

To see all triggers for a table, look in the system catalog pg_trigger

SELECT tgname
FROM   pg_trigger
WHERE  tgrelid = 'myschema.mytbl'::regclass; -- optionally schema-qualified

Works for tables and views.
Or you could use a GUI like pgAdmin that displays the list under the table node in the object browser.
