It's the ACS-Workflow table wf_attribute_value_audit.journal_id and some other tables that depend on journal_issues. So we can't delete the table.
However, the journal_issue__new PL/PgSQL call performs a direct insert into journal_entries after creating the object, so it's completely content-repository ignorant. I guess there have never been upgrade scripts for this ACS 3.4 functionality? 😊
Still, is there a way to cleanly install/uninstall ETP? The acs-workflow is an important part of ]po[ and the goal is to install all of this on top of a clean OpenACS 5.9 installation.
Cheers,
