Why doesn't postgresql.to_sql support a TRUNCATE overwrite_method?

I've mostly used the SDK for loading data into Redshift, so I was surprised to learn that postgresql.to_sql doesn't support a TRUNCATE overwrite_method. I need to preserve table indexes, so dropping the table isn't possible. I read that a PostgreSQL TRUNCATE isn't MVCC compliant. Is that the reason why it isn't supported?

Thanks @senorcinco no I think it's just an oversight. We'll add it to our backlog.
