# Because we need to fire a query to get the settings required for 'restart'

When a restart happens, the database is expected to keep the same settings when it restarts.

To facilitate this, we pre-emptively query and save all database settings after every statement.
So we can use this to set all the settings again after the database restarted.

In the C++ implementation we just copy the ClientConfig options struct and we're done.
