stop rank 30 update on nominatim-docker build

[pdhuvad]

I am installing nominatim-docker 3.0 on VM with 128 GB RAM and 8 vcpus with 1TB disk. I am almost going to run out of disk(only 10 GB left). I am wondering if it is ok to restart pgsql service to stop rank 30 index/update. Here are last few steps of docker file.

    ...
    ...
    ...
    RUN service postgresql start && \
        sudo -u postgres psql postgres -tAc "SELECT 1 FROM pg_roles WHERE rolname='nominatim'" | grep -q 1 || sudo -u postgres createuser -s nominatim && \
        sudo -u postgres psql postgres -tAc "SELECT 1 FROM pg_roles WHERE rolname='www-data'" | grep -q 1 || sudo -u postgres createuser -SDR www-data && \
        sudo -u postgres psql postgres -c "DROP DATABASE IF EXISTS nominatim" && \
        useradd -m -p password1234 nominatim && \
        chown -R nominatim:nominatim ./src && \
        sudo -u nominatim ./src/build/utils/setup.php --osm-file /app/src/data.osm.pbf --all --threads 6 --osm2pgsql-cache 20000 && \
        service postgresql stop
    
    EXPOSE 5432
    EXPOSE 8080
    
    COPY start.sh /app/start.sh
    CMD /app/start.sh

My question: Are rank 30 updates so critical for geocoding?
If I restart postgresql at this stage of installation, would nominatim api be functional?
My current install is for the test purpose and I just want to checkout nominatim local.
