Please check the thread then. Nobody but me has "opined that we should
not worry about fixing it", but then nobody else other than Heikki has
suggested it is even a feature worthy of inclusion, ever. One person
agreed with my position, nobody has spoken in favour of Heikki's
position. However, I had already included the feature on the todo; it
was further down the todo before a second copy was added, second copy
now removed.
If you are saying being able to start Hot Standby from a shutdown
checkpoint is an important feature for you, then say so, and why.
Please also be careful that you don't mix this up with other
improvements, nor say "they all need fixing". This isn't a general
discussion on those points. There are other important things.
