Yes it is, you have made contact with the database and it is telling you 
that serge does not exist as a database user. Per my previous 
instructions try some commands with psql first. Right now we need to 
establish what is possible before getting to the RoR stage. My general 
experience is that if you can't do something with psql then going any 
further is not productive.

So in terminal:

psql -d postgres -U postgres
