Message/events in the plugin when the client is disconnected

[kitty7c6]

Hello, is it currently planned (or perhaps already implemented) to trigger a message/events in the plugin when the client is disconnected from the broker (http)?
I find issues #106 and #215.
Now I can use LWT and send message from remote client before disconnect, but message from plugin will be more interesting for server solution

Hi! Sadly it's neither implemented nor planned, but I'd welcome a contribution to support such case if it was general enough.

same question met on postgres backend, and thinking about if there is a way to fix.
if i can fix the problem, i'll try making the codes go public.

it seems like just do save DB in the struct and just open a connection when interface functions such as GetUser is called.
