Everything that can be configured can certainly be configured using
Slonik; its use shouldn't restrict you in any additional ways.

I don't imagine you can actually get "100% uptime," but that's a
broader issue not particularly relevant to this.  There are some
actions that are likely to lead to some locking of database objects
(see the Slony documentation; each Slonik command has a section
describing locking implications) that would effectively lower uptime
from 100%.
