@john_darksoul @zero Run a Postgres DB in it and try to use pg_repack.
@pernia @john_darksoul @zero Nothing, it's a 3rd extension so 99% of Postgres images you would want to use don't include it. You most likely have to build your own image.
@pernia @john_darksoul @zero Doesn't matter that it is packaged when the Docker image doesn't have it installed. There are people that run 5 different Postgres instances on the same box in different containers, because Docker Compost told them to.

@phnt @john_darksoul @pernia @zero It's generally inefficient to put IO-intensive applications in a container, only somewhat justifiable in cloud-provided k8s clusters with multiple redundancy zones and mostly for databases that natively support clustering, but building customized images is not a problem, you would probably need to do so any way to pin versions in your own docker repository, usually in a repo with it's own CI and compose files dedicated to building base/infrastructure images.
