[#13496] - Postgres datasource does not register any database schema.

We created a Jasperserver datasource that referenced an AWS postgres database. However, it does not register any schema and thus cannot be used to create domains or any other content.

When attempting to create a domain, the domain designer lists all of our tables but none of them show any columns. Each table is prefixed with an underscore character ("_") in lieu of a schema name. Attempting to change the schema is impossible because the 'Select Schemas' button is greyed out.

What could be causing this issue and how can we resolve it?

Thank you.
