Pgpool Global Development Group is pleased to announce the availability of Pgpool-II 4.2 beta1. This is not intended to be used in production but is close to the release version. So users are encouraged to test it out.

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.

V4.2 contains new features and enhancements, including:

• Some items in the configuration file pgpool.conf are vastly enhanced for easier configuration and administration.
• Implement logging_collector for easier log management.
• Implement log_disconnections to collect disconnection logs.
• Implement pg_enc and pg_md5 to allow to register multiple passwords at once.
• Allow to show statistics of health check by using SHOW POOL_HEALTH_CHECK_STATS command, and also allow to show statistics of issued SQL by using SHOW POOL_BACKEND_STATS command.
• New PCP command pcp_reload_config is added.
• Now it is possible to omit write_function_list and read_only_function_list by looking at system catalog information.
• Add new clustering mode snapshot_isolation_mode which guarantees not only data modifications to multiple PostgreSQL but read consistency.
• Support LDAP authentication between clients and Pgpool-II.
• Add ssl_crl_file and ssl_passphrase_command to SSL configuration.
