Suggestion: Add a final success message when import completes

[daishu0000]

Hi team,
When deploying Nominatim, I run the following command to import an OSM file into PostgreSQL:
nohup ../nominatim-venv/bin/nominatim import --osm-file china.osm.pbf > setup.log 2>&1 &
I use tail -f setup.log to monitor the progress. After several hours, the log ends with a line like:
2025-11-28 22:37:58: Recompute word counts
At this point, it's unclear whether the import has completed successfully or if the process has stopped due to an error. There is no explicit final success message in the log.
Suggestion:
It would be very helpful to add a clear message such as:
yyyy-mm-dd hh:mm:ss: Import completed successfully
This would make it easier for users to confirm the import status without needing to cross-check the running processes manually.
Thank you!

That would be useful indeed. I'd also like such a message to report how many minutes in total the import has run. Do you feel like doing a PR for that?

I'm trying to do it.

OK, I have created a PR in #3892
