It does not appear to be so. I grabbed 7.2rc2, and the JDBC driver shipped
with it still implements a batch update with multiple round trips. I
verified this both by sniffing the network packets, reading the shipped
code, and disassembling the Statement class that I'm running. I even checked
the CVS repository at jdbc.postgresql.org.
Am I missing something here?
Thanks,
Tony

Tony,
The batch API works in one round trip in 7.2.
thanks,
