Has there ever been any talk on adding in the ability to import database data through Pulumi? Say by throwing a local SQL file at a database table that's a part of a Pulumi stack?

Definitely - some discussions on this in https://github.com/pulumi/pulumi/issues/127 and https://github.com/pulumi/pulumi/issues/1691. You can also do some of this already today with a combination of (a) code that runs in apply on dependencies (b) runtime.isDryRun to ensure these only run during updates not previews (c) possibly dynamic providers if there is a need to precisely control the lifecycle. There’s lots more we want to do here!

Thanks, I'll see what I can do with what you suggested.
