Ben, I'm working on a project which will let us run liquibase updates
on different DBs. I don't want to make it a part of core, because DBs
can get quite big and it's time consuming, but it should be possible
to set up our CI to trigger it every night or whenever a liquibase
script is updated (don't know if it's possible). I'll let you know
when I'm done with that project!
