 Review comment:
   Nit: I wonder if we just name it getCurrentCatalog(), which returns the name 
of the current catalog. (Same for get current database name. I understand that 
the given name is more explicit, but getCurrentCatalog() is a mirror of the set 
method below and is more consistent with  catalog APIs in which, every get 
(table, database) is named getXxx() instead of getXxxName().
