Well, the problem also exists if add it as an internal database feature --- how long do we wait to consider the standby dead, how do we inform administrators, etc.
True. Though if there is no secondary connected, either because it's not there yet, or because it disconnected, that's an easy check. It's the network lag/stall detection that's tricky.
I don't think anyone says the feature is useless, but is isn't going to be a simple boolean either.
Oh $Deity no. I'd never suggest that. I just tend to be overly verbose, and sometimes my intent gets lost in the rambling as I try to explain my perspective. I apologize if it somehow came across that anyone could just flip a switch and have it work.
My C is way too rusty, or I'd be writing an extension right now to do this, or be looking over that patch I linked to originally to make suitable adaptations. I know I talk about how relatively handy DRBD is, but it's also a gigantic PITA since it has to exist underneath the actual filesystem. :)
