[pgpool-committers: 9423] pgpool: Test: fix occasional 069.memory_leak_extended test failure.

[Tatsuo Ishii]

Test: fix occasional 069.memory_leak_extended test failure.

It turned out that reason of the occasional test failure is, pgpool
child process is gone before running ps command after pgbench
finishes. The cause is a kind mismatch FATAL error, "DISCARD ALL
cannot be executed within a pipeline". To fix this, run pgbench in
background and get the process size before pgbench finishes.
