8.1.11 PREPARE problem?

This is with jdbc3-415. None of the (jdbc, or pg) change logs since then
have mentioned this problem. When run as a prepared statement the first
statement will execute and return results, while the next two seem to
execute, but return no results. When run by hand, not prepared , each
statement runs just fine. when using an older version of the jdbc driver
(7.3?), that does not call PREPARE, things work just fine. Looking at
the logs below, it sure looks like the statements are running, given the
different durations, which are correct for the differences between the
statements. help please.
