[pgpool-general: 8509] Pgpool-II 4.4.0 released.

[Bo Peng]

Pgpool Global Development Group is pleased to announce the availability of Pgpool-II 4.4.0.
This is the first stable release of Pgpool-II 4.4.x.

V4.4 contains new features and enhancements, including:

* Add new dynamic spare process management feature. 
  This feature allows selecting between static and dynamic process management modes.

* Allow to specify replication delay by time in streaming replication mode. 
  For this purpose new parameter delay_threshold_by_time is introduced.

* As PostgreSQL already does, Pgpool-II now supports unix_socket_directories,
  unix_socket_group and unix_socket_permissions for more flexible and precise control of UNIX domain sockets.

* Allow to use comma separated multiple listen addresses in listen_addresses and pcp_listen_addresses. 
  They control which interfaces accept connection attempts,
  which can help prevent repeated malicious connection requests on insecure network interfaces.

* Allow to customize the command used by trusted_servers for checking upstream connection. 
  For this purpose new parameter trusted_server_command is introduced.

* Import PostgreSQL 15's SQL parser.

* Speed up query cache by reducing lock contention. 
  This allows concurrent running clients to fetch cache contents much more quicker.
