JPA, EclipseLink, PostgreSQL and schemas - postgresql

Question

I want to develop a Java EE application with JPA (EclipseLink implementation) and PostgreSQL as database.
I chose to have one database and multiples schemas instead of having multiples databases and one schema per database.
So, in my persistence.xml I have something like that :
<persistence-unit name="00" transaction-type="JTA">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<jta-data-source>todo</jta-data-source>
<class>...</class>
<class>...</class>
<properties>
<property name="javax.persistence.target-database" value="PostgreSQL" />
<property name="javax.persistence.jdbc.driver" value="org.postgresql.Driver" />
<property name="javax.persistence.jdbc.url" value="jdbc:postgresql://localhost:5432/testdb;create=true" />
<property name="javax.persistence.jdbc.user" value="user" />
<property name="javax.persistence.jdbc.password" value="userpwd" />
</properties>
</persistence-unit>
<persistence-unit name="01" transaction-type="JTA">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<jta-data-source>todo</jta-data-source>
<class>...</class>
<class>...</class>
<properties>
<property name="javax.persistence.target-database" value="PostgreSQL" />
<property name="javax.persistence.jdbc.driver" value="org.postgresql.Driver" />
<property name="javax.persistence.jdbc.url" value="jdbc:postgresql://localhost:5432/testdb;create=true" />
<property name="javax.persistence.jdbc.user" value="user" />
<property name="javax.persistence.jdbc.password" value="userpwd" />
</properties>
</persistence-unit>
I can easily reference persistence unit :
EntityManagerFactory emf = Persistence.createEntityManagerFactory("01");
EntityManager em = emf.createEntityManager();
but how can I store information about schemas in persistence.xml ? I want to access schema 00 or 01 in testdb database.
I probably could change schema via native SQL directly but is there a way to bind schema to persistence unit ?
Thank you

This same question was asked and answered here:

You can override the schema for the entire persistence unit using an orm.xml file, or define it within each table annotation or xml element as needed.
