Turning off PostgreSQL breaks these features and can cascade to dependent sidecar processes. Core search, indexing, and dashboard functionality are not affected.\nFor more information see [Sidecar configuration settings](https://help.splunk.com/en/splunk-enterprise/administer/admin-manual/10.4/splunk-sidecars/sidecar-configuration-settings) in the Splunk documentation."
