Yeah, the defaults are way too long for our purposes. The way to get
this set correctly, I think, is to set it in the primary_conninfo
stream on the slave. You end up with something like this:
primary_conninfo='host=blahblah user=bob keepalives_idle=XX
keepalives_interval=XX keepalives_count=XX'
I'm of the opinion that we really need an application-level keepalive
here, but the above is certainly a lot better than nothing.
