How to fix the error PG::ConnectionBad could not connect to server?

Question

System administration

In order to deploy to Hiroku, I transferred my rails project to PG. Now, on the local machine, the browser gives the error
PG::ConnectionBad
could not connect to server
, although everything works fine on Hiroku. I googled a lot about this error ... but understood little. Has anyone come across...

Answer 1

It is possible to hardcode the hasp key server address. For example, at localhost:1947, or in a configuration file.

Answer 2

On Heroku Postgres, that is. Do you have it on your local machine?

Answer 3

I read that I need to edit the pg_hba.conf file but I can’t do it ... it says that access is denied .... damn it, how to get around this?
