Image doesn't have libpq installed anymore?

[louim]

Hey!

I tried switching from circleci/ruby:2.6-node to cimg/ruby:2.6-node, but now my build fail because libpq is not installed by default anymore? Is this supposed to be the case or is it an oversight? This is a rails app with Postgresql at the database, and the pg gem fails to install. Log excerpt from the install:

To see why this extension failed to compile, please check the mkmf.log which can
be found here:

This is intentional but hasn't had much discussion either. I opened an issue on this in another repo for feedback: https://github.com/CircleCI-Public/cimg-base/issues/60

@louim libpq-dev is now installed in this image. Available in the tags: 2.5.8, 2.5, 2.6.6, 2.6, 2.7.1, 2.7 and any releases from today on out.

[FelicianoTech]

Oh and the node-variant tags for these ^ as well.

[louim]

Thanks, I'll give it a try!

Actually, they'll need a few more minutes. They are still building.
