It seems that dpkg calls a package's .config script on a trigger. Should that really happen? If packages are meant to be able to call debconf on triggers, then this would be correct, but if $2 shold really be the name of the trigger (as opposed to the usual version number, as defined by the Debian Policy), then at least $1 shouldn't be "configure" but perhaps "triggered"? > The bad code is: > > # at some points we obsolete major versions within unstable; force the > # obsoletion notifications when upgrading over those > if dpkg --compare-versions "$2" lt-nl 71; then > db_fset postgresql-common/obsolete-major seen false > fi > > I'm not sure how one is supposed to test version numbers in the config > script, but at least that code shouldn't run when triggered. That's true, but right now I can't tell. I committed a simple workaround to postgresql-common (silencing stderr), but cloned the bug against dpkg so that we can discuss/fix the underlying problem.
