Rake db:migrate fails on pg_dump: not in the path on CircleCI 2.0



I am not loading a schema because of some restrictions in my gemset. Thus, I need to build my db with a migration.

Here’s the error when circleci runs rake:db:migrate

rake aborted!
failed to execute:
pg_dump -s -x -O -f /home/circleci/classtag-web/db/structure.sql test_app

Please check the output above for any errors and make sure that `pg_dump` is installed in your PATH and has proper permissions.

Hi Jolim,

You can install pg_dump with sudo apt-get install postgresql-client. You can also build this into a docker image to speed up a build, though I suggest optimizing after you get everything working.


Fantastic. I got it to work. It installs postgresql-client 9.4. I’d like to install 9.6 since our production system is 9.6, and if I try using the image circleci/postgres:9.6-alpine, I get a version mismatch error from pg_dump. I’m not sure if postgresql-client 9.6 even is available for ubuntu 14.04, which I what I think we’re using, right? Otherwise, how do I specify it? I’ve tried the normal route (postgresql-client=9.6) but that doesn’t work.


Seconded, can’t install postgresql-client-9.5 or later, for instance. How can we do that ?


I found the solution:
- run:
name: install postgresql-client
command: |
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
sudo sh -c 'echo “deb http://apt.postgresql.org/pub/repos/apt/ trusty-pgdg main” >> /etc/apt/sources.list.d/postgresql.list’
sudo apt-get update; sudo apt-get install postgresql-client-9.5


For 9.6, I did the following:

  - run: echo 'deb http://apt.postgresql.org/pub/repos/apt/ jessie-pgdg main' | sudo tee /etc/apt/sources.list.d/pgdg.list > /dev/null
  - run: wget --no-check-certificate -q https://www.postgresql.org/media/keys/ACCC4CF8.asc -O- | sudo -u root apt-key add -
  - run: sudo apt-get update
  - run: sudo apt-get install postgresql-9.6 postgresql-client-9.6
