heroku db:pull does not work?

Question

I get the following error message:

heroku db:pull --debug postgres://USERNAME:PASSWORD@localhost/test 
Loaded Taps v0.3.23
Warning: Data in the database 'postgres://USERNAME:PASSWORD@localhost/test' will be overwritten and will not be recoverable.
Receiving schema
Unable to fetch tables information from http://heroku:foo9dsfsdfsdb465ar@taps19.heroku.com. Please check the server log.

The command above does not produce any messages in the log that can be viewed using 'heroku logs'.

Any idea what I am doing wrong?

Answer 1

Use pgbackups instead of taps/db:pull

Answer 2

I answered to similar problem here: Unable to fetch tables information when running heroku db:pull

I found some kind of work-around.
I have the same problem with my SHARED_DATABASE on heroku
ruby 1.9.2
gems:
pg (0.11.0)
heroku (2.32.4)
heroku-api (0.3.5)
taps (0.3.24)
heroku db:pull ended with:
Unable to fetch tables information from http://...@taps19.heroku.com. Please check the server log.

I switched to ruby 1.8.7 using rvm and heroku db:pull works fine.
Back again to ruby 1.9.2 to develop my application.

I hope this help someone until db:pull will be fixed with ruby 1.9.2.

Answer 3

Was able to get it going by reverting back to ruby 1.9.3 and Rails 3.1.0.

Here are some instructions on how to do that with rvm:

$ rvm install 1.9.3
$ ruby -v
$ rvm use 1.9.3-p286
$ rvm gemset create rails310
$ rvm 1.9.3-p286@rails310
$ rails -v
$ gem install rails -v 3.1.0
$ rvm gemset list
$ heroku db:pull –app <yourapp>
$ gem install taps
$ gem install sqlite3
$ heroku db:pull –app <yourapp>
