I think that the level of detail that we *DID* give in the page on
version upgrades was not unsuitable.
http://www.slony.info/documentation/versionupgrade.html

It doesn't try to explain *EVERYTHING*; it tries to give enough detail
to help you construct whatever procedure you need to construct.

The trouble with it all is that:

a) Flexibility comes at a cost, namely the cost of there being some
not-inconsiderable complexity.

Unfortunately, it's not easy, and wishing it were so is just
wishful thinking.

I wish it *could* be easy, but it simply isn't, and I don't see
anything to change that *would* make it easy.

b) People are using different sorts of environments that can vary
quite a bit.

This means that if we write up a super-detailed procedure, that
procedure will ONLY be valid for the specific environment it was
written for.

For instance, I could go into gratuitous detail about how to do
PostgreSQL and Slony-I compiles and installs on our AIX systems,
unfortunately, that detail would NOT be useful to you when you're
using something else.

If, instead, I went into deep detail as to how to deal with a
2-node cluster on Ubuntu Linux, in conjunction with CPanel, this
would:

a) Not be relevant to our staff that aren't using that flavour of
Linux, and
b) Have portions that are totally irrelevant to anyone not using
CPanel.

Super-detailed procedures aren't worth having, sorry.
