Changes
nametag. Eliminates the Prometheus label cardinality explosion caused by the legacy wide-columnsettingsmetric.settingsand remove it from all built-in presets (replaced 1:1 bysettings_numat the same intervals).settings_num: health-check, change-events, postgres-version-overview, recommendations, index-overview (postgres + prometheus variants where applicable).Breaking change
settingsis no longer collected by any built-in preset. Custom dashboards or queries using thesettingstable orpgwatch_settings_*series must migrate tosettings_num/pgwatch_settings_num_value{name="<guc>"}. The metric definition remains available (deprecated) for custom presets.Notes
archive_command,shared_preload_libraries) are intentionally not covered bysettings_num; change detection for them remains available viaconfiguration_hashes.server_version_num.
