In the general sense, yes. :)

For the very specific use case I'm working with (!), things are a bit
different. It's for this, if that helps with context:

* https://github.com/pgautoupgrade/docker-pgautoupgrade
* https://hub.docker.com/r/pgautoupgrade/pgautoupgrade <-- docker
repo

It's a docker container that people use for running PostgreSQL, but
also has the ability to (automatically) upgrade the data files from
older versions. That's the piece I'm working on.

Such a thing is useful for people that need a PG docker container,
and whose needs are fairly simple. They can use point at this one,
and they'll have a self-upgrading PG version that's fairly "fire and
forget".

Thus far (1 month in), it seems to work ok (for us) and some other
people.

Am obviously looking to improve its capabilities over time too. :)
