创建租户的时候存在字符串的字母相同，但是只是大小写不同的资源池，创建租户时报错，

obclient [oceanbase]> CREATE TENANT IF NOT EXISTS sp1 CHARSET='utf8mb4', ZONE_LIST=('obzone1','obzone2','obzone3'), PRIMARY_ZONE='obzone1,obzone2,obzone3;', RESOURCE_POOL_LIST=('Aaaaaaaa_pool_obzone1','Aaaaaaaa_pool_obzone2','Aaaaaaaa_pool_obzone3') , LOCALITY='FULL{1}@obzone1,FULL{1}@obzone2,FULL{1}@obzone3', COLLATE = utf8mb4_general_ci SET VARIABLES ob_tcp_invited_nodes = '%',ob_compatibility_mode = 'MySQL'
    -> ;
ERROR 1242 (21000): Subquery returns more than 1 row

通过SQL 语句查询资源池信息，发现查出来的结果不区分大小写

obclient [oceanbase]> select * from dba_ob_resource_pools where name='Aaaaaaaa_pool_obzone1';
