Distributed tracing is a term for tracing that span between systems. With distributed tracing you can follow request traces across your various services. With pg_tracing enabled in postgres this would extend to your database.

Yes, I know I've been using it for a while.

The hard part is to merge one trace between storage workers, that's where distributed part comes. pg_tracing does nothing for it.

UPDATE: ah I believe I see what you mean -- that it passes down the trace ID.

Yeah, this is for integration with OTEL standard distributed tracing. So you configure some OTEL compliant endpoint for postgres to send trace spans to and that endpoint will collect traces from different services and store them for later retrieval.
