[Pgpool-general] pgpool-II 3.0.4 released

[Toshihiro Kitagawa]

Pgpool Global Development Group is pleased to announce the availability
of pgpool-II 3.0.4, the latest stable version of pgpool-II 3.0 series.

This version fixes various bugs since 3.0.3.

Incompatible changes
====================

- In streaming replication, if delay_threshold is 0 or health
  checking is disabled, the delay checking is not performed.
  This is the behaviour according to a description of the
  pgpool-II manual. But, so far the delay checking was performed
  even if health checking was disabled(Guillaume Lelarge)

Bug fixes
=========

- Fix pgpool-regclass() to be compiled in PostgreSQL 8.0 or later.
  7.4 still produces errors(Tatsuo)

- Fix possible hangup when using /*NO LOAD BALANCE*/ comment in
  streaming replication(Kitagawa)

- Fix hangup when received Flush(H) message or CloseComplete(C)
  message(Kitagawa)

- Fix possible hangup that happen for the receiving timing of
  ReadyForQuery(Z) message after pgpool-II connects to backends(Kitagawa)

- Add description about parameters for recovery_1st_stage_command
  and recovery_2nd_stage_command(Tatsuo)

- Increase size of the internal system catalog cache from 32 to 128.
  This has the effect of reducing "unnamed prepared statement does
  not exist" error(Tatsuo, Kitagawa)

- Fix bug with pcp_connect() which causes double free. Patch
  contributed by Jehan-Guillaume (ioguix) de Rorthais(Tatsuo)

- Fix bug with start_recoery() which is apparently wrong usage of
  PQfinish()(Tatsuo)

- Fix incorrect error message which is sent to the frontend when
  client idle time reached client_idle_limit(Tatsuo)

- Fix "backend status" variable name correctly in pool_status.
  Replace the space with a '_'(Guillaume Lelarge)

- Fix hangup when using md5 authentication method and running as
  daemon. Patch contributed by Nicolas Thauvin(Tatsuo)

- Fix log_per_node_statement so that it prints statements in the
  extended query protocol. This used to work but was broken in 3.0
  (Kitagawa)

Enhancements
============

- Add currval() and lastval() to black_function_list of sample
  configuration files. If they are load balanced, currval() or
  lastval() may be called before the result of nextval() or setval()
  is propagated to slaves(Tatsuo)
