Hello, I am a Trove contributor. I proposed a cherry-pick and lxkong kindly
merged it yesterday! Could someone release the new version as 13.0.1?
Because I believe this bug is significant for users for some reasons.

1. I hit this bug :P

2. One relevant Issue from IRC https://meetings.opendev.org/irclogs/%23openstack-trove/%23openstack-trove.2022-03-11.log.html

3. One relevant issue from https://storyboard.openstack.org/#!/story/2006996

This patch is cherry-picked from master branch and I think this patch has
no risk of regression.

Thanks in advance,
Hirotaka
