This is more generally a matter for the Slony-I discussion list, but I
can touch on the answer here...

Yes, you may use varying kinds of values for hostnames for
"sl_path.pa_conninfo".

I'd expect that to be unwise from the perspective that it means you
need to be looking at network configuration in multiple ways, which I
would expect to lead to a risk of confusion.

If you're clear on everything, and are careful not to get confused,
there's no problem.  I know I'd be likely to get confused when mixing
name and IP addresses.

Further, if your network is configured in such a way that different
hosts see each other differently, that seems likely to have a huge
risk of confusion.  For instance, I could see this happening if two
nodes have DNS configured, and one doesn't.  I rather dislike that
network configuration!  :-)
