NOTICE causing SQLException

Our DBA (which isn't that great of a DBA) changed some settings in
postgresql.conf and suddenly our Java application stopped working with
the following message:

*** TerminalManagerError connecting to the DataBase:
Something unusual has occured to cause the driver to fail. Please report
this exception: Exception: java.sql.SQLException: NOTICE:  Query
statistics are disabled because parser, planner, or executor statistics
are on.

Stack Trace:

java.sql.SQLException: NOTICE:  Query statistics are disabled because
parser, planner, or executor statistics are on.

End of Stack Trace
------------------------------------------------

    Connecting to the DB with 'psql' produced this same 'NOTICE' message.
My understanding of this stacktrace is that the JDBC driver mistook this
'NOTICE' for an error and couldn't open a connection.

    The backend is 7.2 and the JDBC driver is the latest 7.2 stable build.
Can someone please shed me some light? Thank you very much for any help.
