[Pgpool-general] pgpool-II 3.0.5 released

[Nozomi Anzai]

pgpool Global Development Group is pleased to announce the availability
of pgpool-II 3.0.5, the latest stable version of pgpool-II 3.0 series.

This version fixes various bugs since 3.0.4.

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

- Fix bug with the handling of empty queries. The empty queries
  come to be handled the same as SELECT queries. This fix allows
  load-balance after the empty query(Kitagawa)

- Fix insert_lock so that it works correctly even if the column
  definition such as "DEFAULT nextval(('"x_seq"'::text)::regclass)"
  (Kitagawa)

- Fix log message which is emitted when pgpool-II cannot parse the
  query in the extended query protocol so that it shows the query
  (Kitagawa)

- Fix description about backend_weight inpgpool-II manual. It can
 be changed by reloading pgpool.conf(Tatsuo)

- Fix bug which does not update the node status when reattaching the
  node in raw mode(Guillaume Lelarge)

- Fix bug that SELECTs which have subquery with FOR SHARE/UPDATE clause
  are sent to slave/standby(Tatsuo)

- Fix bug which rewriting timestamp of default value fails in PREPARE
  statements. This used to work but was broken in 3.0(Kitagawa)

- Fix crash of pgpool child when frontend connects if in raw mode,
  enable_hba is off and more than 2 backends(Kitagawa)

- Fix some memory leaks(Kitagawa)

-----------------------------------------------------------------------
* Enhancements
-----------------------------------------------------------------------

- Allow time stamp rewriting to work with arbitrary expression in
  default value of a column. Before we detected anything including
  rewriting of default value. for example, timezone('utc'::text, now()).
  Note that, however, this only adopts to simple queries. Extended
  protocols(for example Java, PHP PDO) or SQL "PREPARE" still remain
  same(Tatsuo)

- Change error message "do_md5: read_password_packet failed" into debug
  level(Kitagawa)
