Nonsense? hmmmmmmmm

Without wanting to be hyper-critical, documentation that's hidden isn't
a whole lot of use. The link in your email to
    http://linuxdatabases.info/info/slony.html

does indeed seem to have some more documentation, but why isn't it
linked from the main Slony site
(http://gborg.postgresql.org/project/slony1)?

Why is this documentation on 'Christoper B. Browns homepage rather than
the Slony web pages? The 'official' Slony documentation I had available
was at :
    http://gborg.postgresql.org/project/slony1/genpage.php?howto_idx

and it *really* didn't help with the problems I had.

Having now taken a look at the documentation you reference, it's still
not wonderfully comprehensive. The problem I had was that despite the
fact that my tables had primary keys the Slony configuration refused to
recognise them. The documentation says simply that primary or candidate
primary keys are a requirements.

So - as a potential 'slony user' it is *not* nonsense that there was
negligable documentation - from my perspective it was a fact and I found
an alternative solution.
