I know at least two that complained about it not being 2.0 aware. Not
sure they use it really, but the big error message we have is not good.

One easy way to fix 1.12 is to add a "We don't support Slony 2.0."
message when one clicks on the replication node, and to stop showing
nodes below it.

But we need something for 1.14 or later: either get rid of all, or
support all.

I think Slony 1.2 is working. At least, I haven't seen any bug reports.
Slony 2.0 doesn't.

You mean when 9.2 or 9.3 will be released? when we'll have all those
admin and monitoring capacities? :-D yeah, I know, you're doing quite a
lof of great stuff to make that happen now (now like "in 9.1"). Well,
actually, I do believe this isn't the end of Slony. Not now, not
tomorrow, not still in two years from now.

To answer the question, yeah, we could rename it till we need it for
another kind of replication (the streaming one for instance).
