This is the declarative (PostgreSQL procedures based) partitioning implementation for Zabbix `history`, `trends`, and `auditlog` tables on PostgreSQL. This solution is intended to replace standard Zabbix housekeeping for the configured tables. Partitioning is very useful for large environments because it completely eliminates the housekeeper from the process. Instead of huge DELETE queries on several million rows, fast DDL queries (ALTER TABLE) are executed, which drop an entire partition.
