spring.jpa.hibernate.ddl-auto: update is not creating database sequences

I have a PostgreSQL database with Spring Boot configured to use:

spring.jpa.hibernate.ddl-auto: update

When I start Spring Boot app. Tables are created but sequences configured into entities are not.

I tried with spring.jpa.generate-ddl: true with results in created sequences.

Do you know why this setting is not working for database sequinces?
