Read replica a schema from a non-Supabase postrgres database

I have a non-Supabase postgres database on AWS used by a different department.

I have a Supabase database (not self-hosted) used by my department.

I'd like to do queries that join the data from both databases.

Is there a way to do a read replica or something similar in Supabase so that I have a couple of schemas from the AWS database replicated in?
