Quick Start with Docker
Start the onesparse demo docker container, substitute suitable password and container name:
The container will start detached in the background, verify it's running with 'docker ps'. Now exec a psql process to interact with the container:
$ docker exec -u postgres -it onesparse-demo psql
psql (18.0 (Debian 18.0-1.pgdg13+3))
Type "help" for help.
postgres# select print(random_matrix('int8', 10, 10)) as random_matrix;
