I wonder if it is possible to silently "rewrite" a batched statement to use the CopyManager.
Very(!) roughly speaking: when the first call to addBatch() is made, initialize the CopyManager and provide a a Reader
implementationthat acts as a bridge between the PreparedStatement.setXXX()/addBatch() statements and the CopyManager.
Somethinglike a producer/consumer pattern. The setXXX() calls would prepare a single "line" and the addBatch() would
then"send" this to the CopyManager which is blocked on the Read.readLine() call.
But I have no clue if this would even be possible (blocking Reader.readLine() but sill allowing calls to addBatch() in
thesame Thread seems a major roadblock to me) or - if possible - how much work it would be.
It would definitely require parsing the insert statement passed to the prepareStatement() clause, but as the syntax of
aplain insert statement isn't that complicated, I think that should be doable - especially because we wouldn't need to
worryabout literals as only placeholders will be (must be?) used.
