=========================================================================
pgpool-II 3.1.3
=========================================================================

This is a bugfix release against pgpool-II 3.1.2.

-------------------------------------------------------------------------
* Bug fixes 
-------------------------------------------------------------------------
 - Add m4 files. This should prevent compiling problem on older
   OS's. (Tatsuo Ishii)

 - Fix to handle failover properly in detect_postmaster_down_error().
   (Tatsuo Ishii)

   It is possible that it fails to read backend socket after detecting
   backend errors and before actually detaching the backend. 

 - Fix bug that the process exits before unlocking semaphore by a
   signal interrupt. (Tatsuo Ishii)

 - Fix a memory leak in case of reset_query. (Tatsuo Ishii)

 - Fix pool_ssl_read() to deal with large data reading. (Tatsuo Ishii)

   Original complain is here:
   http://www.pgpool.net/pipermail/pgpool-general/2012-March/000299.html

 - Fix deadlock by enabling log_destination = syslog. (Tatsuo Ishii)
      
   Reported in bug tracker http://www.pgpool.net/mantisbt/view.php?id=9.
   Patch provided by Gilles Darold.

 - Allow to use multi statement in master/slave mode. (Tatsuo Ishii)

   From 3.1 transactional statements such as "BEGIN" are sent to not only
   primary but also standbys. This brings an unfortunate side effect: if
   the multi statement is "BEGIN;DELETE FROM table;END", this will be
   sent to standy as well and cause an error because standby does notallow
   write SQL. So fix is, if a query is a multi statement one, then send it
   to primary only.

 - Allow to have private cache of master node id. (Tatsuo Ishii)
       
   When master goes down running pgpool children look into NULL pointer
   because the process does not connect to the new master yet. The private
   cache returns the old master node id and will avoid the situation.
       
   Per bug reported in http://www.pgpool.net/mantisbt/view.php?id=51

 - Fix pool_start_query() so that it uses my_master_node_id instead of 
   REAL_MASTER_NODE_ID for initial virtual_master_node_id. (Tatsuo Ishii)

   Real master node could be changed while pgpool is running in streaming
   replication mode. Previously it is assigned REAL_MASTER_NODE_ID, which
   could have no connections after fail over and cause segafult.
        
 - Fix pool_setall_node_to_be_sent() to use private_backend_status instead
   of BACKEND_INFO macro. (Tatsuo Ishii)
      
   It is possible that while processing, the node returned by BACKEND_INFO
   is not usable any more.

 - Fix failover(). (Tatsuo Ishii) 

   Before it only restarts worker child only when pgpool child do not need
   restart. This is wrong. We need to restart worker child in any case. 
   Otherwise it continues to send replication time lag check request to down
   the node.

 - Fix debug log message so that it does not contain null characters.
   (Toshihiro Kitagawa)

 - Fix SimpleQuery() so that it restores parser memory context when:
      1) Builtin show commands are used
      2) Parallel query mode
      3) Query cache is used
   (Tatsuo Ishii)

 - Fix hangup when PREPARE statement causes error. (Toshihiro Kitagawa)

   This issue was reported by Tomonari Katsumata:
   Subject: [pgpool-general: 121] question of pgpool's behavior

 - Add doc/pgpool-fr.html to Makefile.am. (Tatsuo Ishii)

   This had been forgotten when the doc was added.

 - Fix  hangup during md5 authentication that occurs in daemon mode
   and log_destination is 'syslog'. (Yugo Nagata)

   Reported in bug tracker http://www.pgpool.net/mantisbt/view.php?id=2.
