> {code}
> 2. {code}CREATE SCHEMA hcatalog{code} should be fine.
> 3. {code}CREATE TABLE hcatalog(hcatalog int){code} should be fine, there is
> no ambiguity for table/column names.
> 4. {code}ALTER DATABASE name RENAME to hcatalog{code} should fail with a
> reserved name error
> {code}"hcatalog" is a reserved name for hcatalog feature integration{code}
> 5. {code}ALTER DATABASE hcatalog RENAME to xxx{code} should fail with a
> system error
> {code}permission denied to ALTER DATABASE hcatalog is reserved for system
> use{code}
