[pgpool-committers: 620] pgpool: Fix long standing memory leak bug with free_select_result

[Tatsuo Ishii]

Fix long standing memory leak bug with free_select_result
since pgpool-II 2.3 was born in December 2009.
Actually this bug only appears when operated in replication mode
(triggered by timestamp rewriting process by coincidence).
