package moodle (not installed) failed to cancel installation: subprocess installed post-installation script returned error exit status 1

Binary package hint: moodle

I was installing Moodle (along with some other software I wanted to check out), and came upon the postgre dialog. Because I did not want to install a database at this time, I attempted to cancel the install by clicking back. Instead of asking if I wanted to cancel the install, it tried to proceed after displaying the dialog several times. I let the install complete, with the intention of uninstalling it afterwards to clean up the failed installation. During the uninstall, I was prompted for my postgre credentials again (even though I was uninstalling).

I think I finally got it uninstalled.
