This is what I want to do: To refer to another database, like I can do it in MySQL. After adding a schema with database name and refering to it from another database I get:

ERROR:  schema "test" does not exist

Adding the database name:

osm_de=# select * from test.test.newt;
ERROR:  cross-database references are not implemented: "test.test.newt"

Could be very simple, if it would be like in MySQL ;) To be completely in context of a schema - so that I can use all tables without the prefix - I have to reset the search_path very often. This is probably not very elegant, but will be my solution then ...

Will it decrease performance to refer to other schemas?

no.  the schemas are simply two namespaces in the same database.
