How to change the default schema of a given user?

Is there any way one can modify the default schema of a given user?

I currently have a system user whose default schema is sytem and I would like to change it to a custom schema I created named test.

This way, given that the table test2 is in the test schema, I can do queries such as:

select * from test2

instead of

select * from test.test2

Edit: I'm aware of set schema test, but I'm looking for something more persistent, something I wouldn't have to do every time I connect to the database.
