This is what I see in the log file:

2004-06-17 11:55:35 [23254] LOG:  statement: PREPARE JDBC_STATEMENT_1(integer) AS SELECT  $1 ; EXECUTE
JDBC_STATEMENT_1(1)
2004-06-17 11:55:35 [23254] LOG:  statement: EXECUTE JDBC_STATEMENT_1(2)
2004-06-17 11:55:35 [23254] LOG:  statement: EXECUTE JDBC_STATEMENT_1(3)
2004-06-17 11:55:35 [23254] LOG:  statement: EXECUTE JDBC_STATEMENT_1(4)
2004-06-17 11:55:35 [23254] LOG:  statement: EXECUTE JDBC_STATEMENT_1(5)
2004-06-17 11:55:35 [23254] LOG:  statement: DEALLOCATE JDBC_STATEMENT_1

I don't know why this would be different for you.  What exact version of
the server and driver are you using?
