is Unsubscribe() required before closing connection? (PubSub)

[HeCorr]

Hello! I was wondering if I should call Unsubscribe() before closing the connection to Redis or if it doesn't really matter since the connection is going to be closed anyway.

Here's the relevant part of my code:

I noticed that go-redis automatically creates a secondary connection for keepalive pings so I had to close both rc and sub, otherwise I would get errors that a closed connection was being used.

Please let me know if there's something flawed in my code. Thanks!

I am also curious about the necessity of using sub.Unsubscribe().

Specifically, I have a websocket endpoint and currently I unsubscribe when the websocket connection closes.

But I'm wondering if the connection to Redis will automatically drop when the Go routine that handled the websocket request ends?
