Pgpool-II 4.4.0 is now released.
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.
Pgpool-II is a tool to add useful features to PostgreSQL, including:
- connection pooling
- load balancing
- automatic fail over and more.
For more information, please see the website.
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.
