Sounds reasonable - something definitely ain't right though. For
example, using the databases created by Slony's test_1_pgbench test, if
I browse the slony_test1 database (the origin), and go to
Replication/T1/Replication Sets/Set 1 - pgbench tables, I can
right-click and select New Object->Add [Table|Sequence]. However, if I
right-click the child sequences or Tables collection nodes, I only get
the Refresh option. Istm that I should get Add Sequence/Add Table on
The same applies to the Subscriptions node on the slony_test2 database -
there is no Add Subscription option. There is one on the Set node (as
there is for Tables/Sequences on the origin), however this throws an
exception when selected.

So how does this work with slonik created clusters (such as I have)? Is
this why I seem to be unable to join existing clusters (the server and
other combos are all blank, even with other nodes running on the local
I'm still new to slony so may be missing something here of course!
