From the docs:
Acquired by the ALTER TABLE, DROP TABLE, REINDEX, CLUSTER, and VACUUM FULL
commands. This is also the default lock mode for LOCK TABLE statements
that do not specify a mode explicitly.
Now is the lock in question created explicitly with LOCK TABLE?
Since the docs dont say a thing about triggers acquiring locks.
