And I don't want to run `CREATE INDEX IF NOT EXISTS` every time through the loop.\r\n\r\nThis should work like the `foreign_keys=` mechanism.\r\n", "repo": {"value": 140912432, "label": "sqlite-utils"}, "type": "issue", "active_lock_reason": null, "performed_via_github_app": null, "reactions": "{\"url\": \"https://api.github.com/repos/simonw/sqlite-utils/issues/349/reactions\", \"total_count\": 0, \"+1\": 0, \"-1\": 0, \"laugh\": 0, \"hooray\": 0, \"confused\": 0, \"heart\": 0, \"rocket\": 0, \"eyes\": 0}", "draft": null, "state_reason": null}
