I assume you can do this without driver changes by preparing a suitable
statement. Presumably you'd do something like prepare a 20-row-insert
statement, use it until you have less than 20 rows left, then prepare
and use single-row-inserts for the remainder.

It prepares them once and sends a pair of Bind/Execute messages for each
set of parameter values, with a Sync at the end. You can see the details
