This is useful for cases where you want to add resiliency to DNS lookups
for redis and postgres, so they will continue to work even if there is
a DNS outage
This restores the previous functionality. The script now allows the following options:
* `discourse backup` (uses the system generated filename)
* `discourse backup <some_filename>` (uses the provided filename)
* `discourse backup </some/path/to/filename>` (moves the backup to the provided path with the given filename)
Remote backup stores do not support the last option.
Some file extensions (like `.tar.gz`) are automatically removed from the provided filename.
- By default, behaviour is not changed: tags are made lowercase upon creation and edit.
- If force_lowercase_tags is disabled, then mixed case tags are allowed.
- Tags must remain case-insensitively unique. This is enforced by ActiveRecord and Postgres.
- A migration is added to provide a `UNIQUE` index on `lower(name)`. Migration includes a safety to correct any current tags that do not meet the criteria.
- A `where_name` scope is added to `models/tag.rb`, to allow easy case-insensitive lookups. This is used instead of `Tag.where(name: "blah")`.
- URLs remain lowercase. Mixed case URLs are functional, but have the lowercase equivalent as the canonical.
