PostgreSQL is peculiar in that it has the hierarchy server->database->schema->table instead of the common server->database->table. Tables are known as "database tables" and not "schema tables", so the introduction of a level between "database" and "table" is clearly non-standard and IMHO clearly wrong. I have yet to see a method of switching between one database and another in postgres within the same connection, so Radicore does not support this. This means that all the schemas which you wish to access *MUST* reside in the same database. It is possible to open multiple connections to different servers, but it is not possible for a single database transaction to span multiple connections.
