ddev: Pantheon ddev pull fails after download, during import.

What happened (or feature request):

I tried to do a ddev pull, got the following error:

~/Sites/artist [master*]$ ddev pull
You're about to delete the current database and files and replace with a fresh import. Would you like to continue (y/N): y
Importing database... 
Could not perform import: Failed to run docker-compose [-f /Users/michael/Sites/artist/.ddev/docker-compose.yaml exec -T db bash -c cat /db/*.sql | mysql], err='exit status 1', stdout='ERROR 1227 (42000) at line 6894: Access denied; you need (at least one of) the SUPER privilege(s) for this operation
', stderr='' 

I had just done a ddev start on an existing codebase that I hadn’t used DDEV for previously.

What you expected to happen:

The pull to be complete.

How to reproduce this:

I could share the project with someone, I suppose…

Please use a complexity rating of 1-5 (5 is high) for a feature request. (High complexity implies more PR planning)
