pgpool-II 3.1.1 
=========================================================================

This is a bugfix release against pgpool-II 3.1.

-------------------------------------------------------------------------
* Bug fixes 
-------------------------------------------------------------------------

- Fix add_regex_pattern(). It does not allocate enough memory for each
  black/white_function_list items. The function adds "^" and "$" to each
  function items which do not contain those characters. Unfortunately the
  function forgot to add extra 2 bytes for those characters. This may lead
  to memory corruption errors when pgpool starting up.

- Fix error message of check_replication_time_lag(Tatsuo Ishii).
  It emitted wrong error message when it failed to connect to PostgreSQL
  while checking streaming replication delay. Because it does not use
  health_check_user anymore.

- Fix memory leak(Toshihiro Kitagawa).
  This is essentially same as the fix made for 3.0.5(commit
  19a4ea9215da0b61728741fc0da2271958b09238).

- Major cleanup for strncpy(Tatsuo Ishii).
  There are several places where strncpy() is used. Problem is some of
  them do not consider the case when copy lengh == buffer size. In this
  case copied buffer is not null terminated and may cause tons of problems
  later. To fix this, most of them are replaced by strlcpy().

- Update cached backend status whenever possible(Tatsuo Ishii).
  This solves the problem of follow_master_command not being able to
  lookup backend status correctly which was reported by Jeff Frost:

    Subject: [Pgpool-general] diagnosing BackendError from pcp_recovery_node
    To: pgpool-general at pgfoundry.org
    Date: Wed, 05 Oct 2011 15:15:07 -0700 

- Fix buffer overrun problem when pcp password is longer than 32(Tatsuo
  Ishii).

- Remove PGDLLIMPORTI which is only neccessary for Windows and cause a
  problem for non gcc. Patch contributed by Ibrar Ahmed.
