Start to learn how to add Pgsql. Would it be better to create new branch or do it in the same as before?

[webknjaz]

sure, new branch per feature. here's an example: https://github.com/tailhook/vagga/blob/master/examples/tutorials/django/vagga.yaml#L98-L112

[webknjaz]

and here's an example of doing cross-container locks: https://github.com/GDG-Ukraine/gdg.org.ua/blob/master/vagga.yaml#L126-L129
