[Feature] Support SQL string composition

The redshift connector currently supports parameterised queries (aka bind variables) which is great.

However some of our use cases require other parts of a Redshift SQL query to be dynamically created. These include components such as the table name, the schema... and are commonly referred to as Identifiers. For example ``` f"SELECT * FROM {schema}.{table}"```

Other libraries such as [pg8000](https://github.com/tlocke/pg8000#many-sql-statements-can-t-be-parameterized) and [psycopg](https://www.psycopg.org/docs/sql.html) have developed modules to escape these variables via identifiers.

Beyond usability, the main advantage of this approach is that it helps with SQL injection attacks.

Inizia esaminando il supporto esistente del connector per le query parametrizzate, quindi confronta gli approcci alla composizione degli identificatori documentati da pg8000 e psycopg. Il lavoro è completato quando gli utenti possono comporre in sicurezza identificatori Redshift dinamici, come schemi e nomi di tabelle, con protezione contro SQL injection.
