Refused connection with an unknown character set
proxysql --version now print to stdout instead of stderr
- Add support for com_field_list command
- If the select statement used in a multi-statement command, or if the select statement parsing unsuccessful, multiplexing and routing query is disabled, the client still bound to a single back-end connectivity
