How to create a hibernate view of other databases?

Good Morning, I’m in a problem!

My project is multitenant, I use SPRING JPA + SPRINGBOOT + POSTGRES. Where it contains a database manager and Each tenant has its own database.

The problem starts when inside the database of the tenant I have views of the data manager database.

For example, inside the database manager I have information to make the login of the users of a tenant. But in the database of each tenant should be able to have the information of their users. Where users within the tenant database could have more data!

What is the best way to do this? Should I create the view?

In addition, this application is very popular, so the idea is that the use of the database is quite dynamic.

Thank you in advance! any contribution will be helpful.
