Loading a Driver

Before using the driver, perform the following operations:
1. Decompress the driver package of the corresponding version and copy psycopg2 to the site-packages folder in the Python installation directory as the root user.
2. Change the psycopg2 directory permission to 755.
3. Add the psycopg2 directory to the environment variable $PYTHONPATH and validate it.
4. For non-database users, configure the lib directory in LD_LIBRARY_PATH after decompression.
Load a database driver before creating a database connection:
```
import  psycopg2
```
