I think the extended `USE ... IN ...` syntax is already very powerful, the only missing case is to switch to a catalog and its default namespace. Since we need a new syntax for it anyway, how about `SET CURRENT CATALOG ...`? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
