Hey John

Thanks for posting in the Lucid Community! 

a.) Yes -- you can export your ERD diagram. To learn a bit more about this check out our ERD article from our Lucid Help Center. 

b.) We don't currently support that database for ERD import but you could write a custom query and run it in your database if you'd like. If you are able to generate an output file in the format our ERD importer expects you should be able to import successfully. If you'd like an example output file from a PostGreSQL import for reference please reach out to us at support@lucidchart.com -- I'd be happy to provide that for you! 

Hope this helps -- please let me know if you have any other questions! 

The link for ERD article does not exist any more.  Will you please provide the updated location?
