When i use 0.17.1 client connect to the mysql 5.5.10 and exec query sql, there is a exception: Error 2027 (HY000): MySQLToType(15,0) failed: unsupported type: 15

But it's perfect connect to mysql 5.7.28.

Is there something wrong go here ? how do I to fix it?

Mysql 5.5 is very old. Would accept a PR adding docs saying this version is not supported.
