UUIDs fail with EclipseLink and Postgres

[mswatosh]

When creating a query with a UUID, the parameter is set as a VARCHAR instead of a UUID, and is rejected by Postgres.

Here is an example of the failing query:

UUID uuid = p1.id;
List<?> result = em.createQuery("SELECT p FROM PurchaseOrder p WHERE p.id=?1")
                   .setParameter(1, uuid).getResultList();

There is some discussion on how to convert to a UUID in postgres here:

There is a recreate here (see the /uuid endpoint):
