Batch write to temporary table

**Is your feature request related to a problem? Please describe.**
An ETL application I maintain does batch writes to temporary tables in Clickhouse which requires that a batch be bound to the specific connection that created the table. It doesn't seem to be possible to use the new native interface and have such granular control over the batch's connection.

**Describe the solution you'd like**
I'm open to any solution. The most obvious to me would be to export the acquire and release functions as well as the connect struct and it's funcs.
