I know. I wrote the original jdbc driver binary transfer code because I wanted better performance.
But you clipped half of my sentence it stars with:
"An alternative is to request binary transfers from the first query" - meaning that the debug feature
is the performance killer that requests binary transfers for also the first query by doing a backend
round-trip to describe what kind of in/out parameters the operation contains - before executing the
actual statement.
It is currently used by jdbc driver unit test framework so that every operation need not be tried n
times in unit tests to verify that the binary transfers work for all operations.
