Short answer is "yes", but I would keep in mind that Kubernetes isn't just one monolithic tool, it's a toolbox and you don't have to use all of its features for everything. It's absolutely fine to pin your Postgres to a handful of pre-selected hosts with locally attached storage fully exposed to a Postgres container. Yes, this won't be semi-magically "moving databases around" (not needed in most cases) but you'll still be getting other k8s benefits I listed above. But even if you feel adventurous and want to have a fully dynamic storage under your RDBMS, there are tools for this now in open source / commercially supported form [1].
