A.46. Release 4.3.9

Remove restore_command from sample scripts. (Bo Peng)

Restore_command is not required because replication slot is enabled. It causes occasional failover failure.

Fixed the default values of recovery_user, failover_on_backend_shutdown and insert_lock. (Bo Peng)

Because the default value of recovery_user should be same as health_check_user and sr_check_user, I changed the default value from '' to 'nobody'.

The correct default value of failover_on_backend_shutdown should be "false" and the correct default value of insert_lock should be "on".

Fixed statement_level_load_balance with BEGIN etc. (Tatsuo Ishii)

When statement_level_load_balance is enabled, BEGIN/END/COMMIT/ABORT/SET/SAVEPOINT/RELEASE SAVEPOINT/DEALLOCATE ALL/DISCARD were sent to primary node and all standby nodes even if load_balance_mode is off. This is not only plain wrong but caused slow down if one of the standby nodes are in remote network.

Fix this in that pgpool sends such queries to primary node only when load_balance_mode is off.
