How to use db:pull

Vitalis

Answer 1

First, you need to fix your connection string: use postgres instead of postgresql.

You will need to have the pg db adapter installed to use Sequel's postgresql adapter:

gem install pg

You may also want to make sure your taps, sequel, and heroku gems are up to date:

gem install heroku taps sequel

Then try your heroku db:pull again. If that doesn't work, post a comment or hop in #heroku on Freenode and we can try to help.

Your connection string is wrong. Try:

heroku db:pull postgres://root:@localhost/db_name

Jeremy is right, totally missed that you used 'postgresql' instead of 'postgres'. – Lutes

I had to use a connection URL in the command like this: heroku db:pull postgres://@localhost/my_local_db -- in other words I didn't have a user named root. – Yammer

Answer 3

Started working fine once I upgraded the "pg" gem from version "0.11.0" to "0.12.2".
