commit    bcecfcc8bbd045cc15f6b5d1b75ba31b41f3f912
Author:   Tatsuo Ishii <ishii@postgresql.org>
Date:     Wed Dec 03 02:12:22 2014 +0000

    Add memory leak regression test.
    
    The test executes pgbench -S for a while (currently 30 seconds) and
    compare pgpool child process size before and after. If it increases,
    the test fails. The test is executed in streaming replication, native
    replication and raw mode.
