Description
### Is your proposal related to a problem?
For streaming PG subscriptions against a pool of Hasura servers (only a single PG) that are behind a single IP proxy/load-balancer, are sticky sessions required?
It looks like the state is on the server which implies yes, but maybe that state is stored in PG so would be shared so they are not needed?
### Describe the solution you'd like
We can update the docs to cover this topic under streaming subscriptions.
