This feature can be used as follows:
```
client.query({ text: 'SELECT 1', queryMode: 'extended' })
```
This will force the query to be sent with parse/bind/execute even when it has no parameters and disallows multiple statements being executed. This can be useful in scenarios where you want to enforce more security & help prevent sql injection attacks...particularly by library authors.
