About binaryTransfer.

Hi,

I have a peformance trouble with 9.3-1100 driver.
Running same application(*) with 9.2-1004 and 9.3-1100,
It does another behavior.
(*) Retrieving 9990 rows with preparedStatement.

9.2-1004:
Always flags = 16.
----
14:09:55.730 (1) simple execute,
handler=org(dot)postgresql(dot)jdbc2(dot)AbstractJdbc2Statement$StatementResultHandler(at)8232a5d,
maxRows=0, fetchSize=0, flags=16
14:09:55.878 (1) simple execute,
handler=org(dot)postgresql(dot)jdbc2(dot)AbstractJdbc2Statement$StatementResultHandler(at)34e671de,
maxRows=0, fetchSize=0, flags=16
----

9.3-1100
Repeatedly flags = 48 and 16.
The count of "flags=16" is same with 9.2-1004, so
"flags=48" is extra executing.

It seems that binarytransfer mode is good at dealing with
big-data(many columns?many rows?), but some packets are
sent/received for this function, right?

I want to make 9.3-1100 driver do old behavior like 9.2-1004.
What can I do ?
