documentation about explicit locking

Hi.

I wonder why we mention on the following page that CREATE COLLATION
requires SHARE ROW EXCLUSIVE lock

https://www.postgresql.org/docs/devel/static/explicit-locking.html

I know that's the lock taken on the pg_collation catalog, but do we need
to mention locks taken by a DDL command on the catalogs it affects?  All
other commands mentioned on the page require to specify the table name
that the lock will be taken on.

Thanks,
Amit
