Maybe the INFORMATION_SCHEMA can be lower case?

We can see the dbeaver will send query :

SELECT * FROM information_schema.TABLES t\nWHERE\n\tt.TABLE_SCHEMA = 'information_schema'\n\tAND t.TABLE_NAME = 'CHECK_CONSTRAINTS'

Now we db name and table name in information_schema are uppper case. But the columns in information_schema is lowwer case.

Now in planner v2 we has already support

| unquoted_ident_case_sensitive  | 0          | 0          | SESSION | Case sensitivity of unquoted identifiers, default value: 0 (aka case-insensitive).                  | UInt64 |

So maybe the db name and table name can set to lowwer case?
