Another solution would be to create a view based on a function and pass the schema name to the function.

But,  I think you have to rethink your server configuration and may be whole development environment. One server for  live data and staging, testing , training ... I found that really dangerous

Wouldn't it be easier to create a view in each schema with the
appropriate search_path?

That way, you get the view that your search_path points to, which then
in turn uses the tables from the search_path in use when the view was
created.
