It seems like Postgres isn't really doing anything here in the benchmark besides acting as a host for XGBoost? It needs to load the model parameters from the database whereas the Python microservice is reading the model parameters from a model.bin file in the filesystem. Both are one-time costs presumably (I'm guessing the SQL that loads the model keeps the model around in memory which seems reasonable given its performance gap to Python).

So it seems like what is needed is a better host for XGBoost models instead of having to install, maintain and launch an entire database? Or am I missing something here?

I think what you're missing is that XGBoost is worthless without data to use for inference. That data can come from in process, or over the wire. One is fast, one is not.
