It should be added here that QGIS (as a client) caches data in a local
Geopackage (Even Rouault knows more about this). So the perfomance
issue when consuming WFS isn't that bad.
On the other hand, I experienced bad user experience when using
PostgreSQL/Postgis over slow network connections - the PostgreSQL data
over the network isn't compressed/optimized and the latency can be
So there is not a clear and easy answer to your question.
If you have a lot of "relations" in your data, I would definitely do
PostgreSQL with transaction mode (for editing in particular).
