Comment 1 for bug 878509

Hi Liam, thanks for taking the time to file this bug and help us make the juju charm collection better!

Indeed, the usernames and database names must conform to this documentation:

http://www.postgresql.org/docs/current/interactive/sql-syntax-lexical.html

Section 4.1.1 defines the allowed chars, of which '-' is not one of them.

The fix is to change the -'s to _'s.
