I sucessfully installed prisma and I'm able to create und query data. When opening pgadmin I noticed, that I have a lot of databases and I have trouble finding the oen with my data in case I have to troubleshoot something

Prisma uses the one you supply in the connection string, and potentially a temporary one as the shadow database.

My bad. Wasn't something about prisma. Because I had my settings wrong I could see all databases on the cluster.
