Comment 1 for bug 1987909

I can confirm that `attr-sql` support was dropped in November 2019 (so for Focal 20.04) as it was deemed too uncommon to support by default (that's what the changelog entry for 5.8.1-1ubuntu1 implies).

Sorry to hear that you depend on those. I'm not familiar with it myself but maybe the strongswan mailing list (https://lists.strongswan.org/mailman/listinfo/users) could help you figure a different way to accomplish what you need without the `attr-sql` plugin?
