PgOSM Flex provides high quality OpenStreetMap datasets in PostGIS using the osm2pgsql Flex output. See https://pgosm-flex.com/ for the main project documentation.
If the custom domain is not working, try https://rustprooflabs.github.io/pgosm-flex/index.html. If everything is working this link will redirect to the custom domain.
See ./docs/README.md for instructions to build and view the documentation locally.
