Every telegraf.* metric table is now a daily time-range partitioned parent managed by pg_partman. Retention drops old partitions instead of the row-by-row DELETE that so-telegraf-trim used to run nightly, and dashboards will benefit from partition pruning at query time. - Load pg_cron at server start via shared_preload_libraries and point cron.database_name at so_telegraf so job metadata lives alongside the metrics - Telegraf create_templates override makes every new metric table a PARTITION BY RANGE (time) parent registered with partman.create_parent in one transaction (1 day interval, 3 premade) - postgres_telegraf_group_role now also creates pg_partman and pg_cron extensions and schedules hourly partman.run_maintenance_proc - New retention reconcile state updates partman.part_config.retention from postgres.telegraf.retention_days on every apply - so_telegraf_trim cron is now unconditionally absent; script stays on disk as a manual fallback
