PG::ConnectionBad FATAL: role “Myname” does not exist

Question

I am trying to use PostgreSQL so that I can deploy to Heroku. However I cannot run localhost anymore why? I get the following message:

PG::ConnectionBad
FATA         


        

Answer 1

The error is "role "Myname" does not exist",

create the user "Myname" for Postgresql

sudo -u postgres createuser --superuser Myname

it will solve this issue.
