auto_setup works with DBAL v4, isn't it?
what doesn't work is migrations, which cannot be generated because DBAL v4 doesn't provide any practical hook to add extra SQL to migrations.

Yes, auto_setup does work with DBAL 4 for creating tables. However, as noted in the changes, it does not automatically create PostgreSQL function and trigger

Even when not using the migrations but using auto_setup? 😢

here are the output of symfony console doctrine:schema:update --dump-sql command
DBAL 3

CREATE TRIGGER notify_trigger AFTER INSERT OR UPDATE ON messenger_messages FOR EACH ROW EXECUTE PROCEDURE notify_messenger_messages();;
DBAL 4
CREATE TABLE messenger_messages (id BIGINT GENERATED BY DEFAULT AS IDENTITY NOT NULL, body TEXT NOT NULL, headers TEXT NOT NULL, queue_name VARCHAR(190) NOT NULL, created_at TIMESTAMP(0) WITHOUT TIME ZONE NOT NULL, available_at TIMESTAMP(0) WITHOUT TIME ZONE NOT NULL, delivered_at TIMESTAMP(0) WITHOUT TIME ZONE DEFAULT NULL, PRIMARY KEY (id));

CREATE INDEX IDX_75EA56E0E3BD61CE ON messenger_messages (available_at);
CREATE INDEX IDX_75EA56E016BA31DB ON messenger_messages (delivered_at);
both using Symfony 7.4, and use_notify: true, and auto_setup is not defined (i guess the default value is true)
