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](https://www.pgpool.net/). 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. You can download it from [here](https://www.pgpool.net/mediawiki/index.php/Downloads).
