[Feature Request] Allow users to manually reconnect to the database.

[cnwangjie]

Describe the solution you'd like

In my usage, the existing connection often becomes unavailable after the network condition switches. This may be because the application is still attempting to use the previous connection. An EOF or Load Failed error may be occurred.

However, when I restart the app or switch the current data connection, I can successfully complete the query.

So I hope the app allows users to manually reconnect to the database.
