postgreSQL: see trigger dependencies of an extension

Source: How to select functions that belong in a given extension in PostgreSQL?
The StackExchange question shows this is the request to use:

SELECT e.extname, ne.nspname AS extschema, p.proname, np.nspname AS proschema
FROM pg_catalog.pg_extension AS e
    INNER JOIN pg_catalog.pg_depend AS d ON (d.refobjid = e.oid)
    INNER JOIN pg_catalog.pg_proc AS p ON (p.oid = d.objid)
    INNER JOIN pg_catalog.pg_namespace AS ne ON (ne.oid = e.extnamespace)
    INNER JOIN pg_catalog.pg_namespace AS np ON (np.oid = p.pronamespace)
WHERE d.deptype = 'e'
ORDER BY 1, 3

which led me to use

SELECT e.extname, t.tgname
FROM pg_catalog.pg_extension AS e
JOIN pg_catalog.pg_depend AS d ON (d.refobjid = e.oid)
JOIN pg_catalog.pg_trigger AS t ON (t.tgfoid = d.objid)
where e.extname = 'mbqt_shared_api'
