    Use a background migration for issues.closed_at · 78d22fb2
    Yorick Peterse authored
    In a previous attempt (rolled back in
    gitlab-org/gitlab-ce!16021) we tried
    to migrate `issues.closed_at` from timestamp to timestamptz using a
    regular migration. This has a bad impact on GitLab.com and as such was
    rolled back.
    
    This commit re-implements the original migrations using generic
    background migrations, allowing us to still migrate the data in a single
    release but without a negative impact on availability.
    
    To ensure the database schema is up to date the background migrations
    are performed inline in development and test environments. We also make
    sure to not migrate that that doesn't need migrating in the first place
    or has already been migrated.
