Error line from logs: ERROR: No support for database client postgres

If you are using postgres (usually for heroku users), just change your config.js file from:

production: { url: 'http://hakanu.net', mail: {}, database: { client: 'postgres',

to

production: { url: 'http://hakanu.net', mail: {}, database: { client: 'pg',

Redeploy your ghost.
