Many-to-many: select an entity by matching relationship

I have a many to many relationship implemented: CREATE TABLE public.message ( id BIGSERIAL PRIMARY KEY, name varchar(40) UNIQUE NOT NULL ); CREATE TABLE public.package( id BIGSERIAL PRIMARY KEY, name varchar(40) UNIQUE NOT NULL ); CREATE TABLE public.package_to_message ( message_id BIGINT NOT NULL, package_id BIGINT NOT NULL, CONSTRAINT package_to_message_pk PRIMARY KEY (message_id, package_id) ); I need to select a package that has an association with a precisely defined set of messages [message_name_1, message_name_2, message_name_3]. With all of the above and none more. Is it possible to do this using a more or less optimized query? Nothing comes to mind.
