While trying to restore/rebuild discouse It always end with database migration error  
current version:20220818171849  
restored version:20150822141540  
.  
.  
.

```plaintext
relation "digest_unsubscribe_keys_pkey" already exists in schema "public" (PG::DuplicateTable)
CONTEXT: SQL statement "ALTER TABLE backup.unsubscribe_keys SET SCHEMA public;"
PL/pgSQL function inline_code_block line 11 at EXECUTE

```

I’ve also tried to rename/delete this database during migrate process but it failed to.

Is there a way to update this old version to current discourse version?
