Certainly it's licensed.  You may avail yourself of the copyright notice.

The main developers are mostly employees of Afilias who are a major
user of the software, and while we have some particular support
responsibilities there, we don't really have any mechanism for
offering support more widely.

A number of the Postgres consulting firms have expertise with Slony,
and if you solicit assistance on the list, I'm sure some of them are
on the list and could contact you off-list to explore service
offerings and fees.
