Note that the approach Aakash is taking doesn't involve changes to
the backend code, it is strictly a standalone executable to which
functions as a proxy to a hot standby and to which clients like
replications systems connect. There is a possible additional
configuration which wouldn't require a hot standby, if time permits.
I am not clear on whether 2nd Quadrant's code takes this approach
or builds it into the server. I think we need to know that much
before we can get very far in discussion.
