From a63d4cc9e96c1f5bb9c5bb9fc9119fb137de3b1b Mon Sep 17 00:00:00 2001 From: Sean Quah <8349537+squahtx@users.noreply.github.com> Date: Wed, 25 Jan 2023 13:38:53 +0000 Subject: Make sqlite database migrations transactional again (#14910) #13873 introduced a regression which causes sqlite database migrations to no longer run inside a transaction. Wrap them in a transaction again, to avoid database corruption when migrations are interrupted. Fixes #14909.
