Is Postgres sidecar loaded on-demand?

[yuanliu]

We do not use features that require postgres sidecar, and do not see postgres being started.  Does this mean that the sidecar is loaded only when a feature calls for it?

@yuanliu - I believe Splunk added Postgres binary for KVstore to be migrated from MongoDB to Postgres. But I don't think migration has yet happened, even though Postgres is enabled by default in server.conf, auto migration is disabled by default. And I don't think Postgres is documented to be used anywhere else in Splunk currently.
