Pgpool Global Development Group is pleased to announce the availability of Pgpool-II 4.2.0.
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/). V4.2 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. * Import PostgreSQL 13's SQL parser.
