Read/Write Connections

DuckDB has two access modes:

1. Read/Write: One process can both read and write to the database.
2. Read Only: Multiple processes can read from the database, but no processes can write.

If you open another connection to a database that is already open in read/write mode, you may get an error. Close the read/write connection to resolve this.
