timescaleDB has an open source product that lets you ingest opentracing data into postgres:

You're probably thinking that observability data is time-series data that relational databases struggle with once you reach a particular scale. Luckily, PostgreSQL is highly flexible and allows you to extend and improve its capabilities for specific use cases. TimescaleDB builds on that flexibility to add time-series superpowers to the database and scale to millions of data points per second and petabytes of data.

Today, we are announcing the general availability of OpenTelemetry tracing support in Promscale, the observability backend for metrics and traces built on the rock-solid foundations of PostgreSQL and TimescaleDB. We’re now closer to becoming the unified data store for observability powered by SQL, bringing the PostgreSQL and observability worlds together.
