Used in Hibernate/Java criteriaBuilder.

However, it's worth noting what the Postgres docs have to say on TIMETZ:

The type time with time zone is defined by the SQL standard, but the definition exhibits properties which lead to questionable usefulness. In most cases, a combination of date, time, timestamp without time zone, and timestamp with time zone should provide a complete range of date/time functionality required by any application.

But that said, it might be important for us to support this in order to improve our drop-in compatibility with existing Hibernate applications.

Related to #16490.

@solongordon do you have any estimate of how much work implementing this might be given the existing work on TIME?
