Hi,  
I am trying to set up temporal with our vitess cluster (mysql version 8.0). Seems that the SQL client Temporal is using is not compatible with our vitess cluster when have “multiStatements” flag enabled. But I can use a different MySQL go client to connect to vitess with that flag enabled.

I comment out the below line and built a Temporal server docker image, it worked well with our vitess cluster.

I also filed an issue on github: [sql client is not compatible with mysql version 8+ · Issue #1364 · temporalio/temporal · GitHub](https://github.com/temporalio/temporal/issues/1364)

Ya, i know 8.0 is not officially supported, but it worked with a different sql client. so it is less likely a mysql server issue
