Thanks for the PR!

What if the database name contains a backtick? I think that's a valid name: https://clickhouse.tech/docs/en/query_language/syntax/#syntax-identifiers

There are other places where config.DatabaseName is used and config.MigrationsTable will have the same problem. Let's completely fix this issue by:

1. Adding an escaping or quoting method to quote identifiers like pq's
   • Don't forget to add tests for this
2. Updating all usages of config.DatabaseName and config.MigrationsTable to use the quote identifier method above
