-- Create a login role for ambassador
CREATE USER ambassador;

-- Use this if your deployment uses passwords rather than peer authentication:
-- ALTER ROLE mastodon_ambassador WITH PASSWORD 'something secret, hopefully';
--
-- Note that PostgreSQL supports setting “encrypted” (hashed) passwords,
-- which is a better option if the password must be stored in some configuration
-- management tool.
