- Currently we prompt a user for a username to dump their Ghost database with which can be confusing if users can't remember their database details
- The Ghost user _likely_ has the required permissions to dump the database itself so we can first try that without prompting the user and _then_ prompt them if it doesn't work
- We added `--no-tablespaces` to the dump command to try and reduce the likelyhood of hitting users not having the `PROCESS` permission since most hosted DBs don't let this and Ghost's DB setup doesn't require DBs be dumped with that anyway
