Method insert

src/expr-parser/src/catalog.rs:35–53

Registers an object in the catalog. Specifying `transient` as true allows the object to be deleted by [Self::remove_transient_objects]. Returns the GlobalId assigned by the catalog to the object. Errors if an object of the same name is already in the catalog.
