Description
Description
Inspired by the mailing list thread at https://externals.io/message/128741.
To make the use of persistent connections with MySQL somewhat safer, MySQLnd should send a connection reset when “restarting” a persistent session.
According to https://dev.mysql.com/doc/c-api/8.4/en/mysql-reset-connection.html, MySQL should then take care of cleaning up all connection-specific state.
