Default Sequence Generator Strategy for Grails 3 and Grails 4

When using PostgreSQL together with Grails, one thing that has annoyed me when creating domain classes is that I have to manually add a line for telling hibernate how it should create, name and use the sequences.

Finally Hibernate now has a new SequenceStyleGenerator this solves this:

Create your application.groovy file, application.yml will not work and write this:

grails.gorm.default.mapping = {
    id (
            generator: 'org.hibernate.id.enhanced.SequenceStyleGenerator',
            params: [prefer_sequence_per_entity: true]
