How to use Postgres date_trunc via CriteriaApi in Hibernate 6

Hibernate ORM
2

You can pass
new SqmExtractUnit<>( TemporalUnit.DAY, ((NodeBuilder) cb).getIntegerType(), (NodeBuilder) cb ) instead of cb.literal("day"). We don’t have an API yet for constructing such extract and duration units, but ultimately I envision a method in HibernateCriteriaBuilder to invoke the date_trunc function.
