Currently, all of sloniks commands are implemented in pgAdmin, with some 
differences:

- FAILOVER not implemented yet (execution logic reengineered from slonik 
is available)

- Merging set is implemented for subscribed sets (the normal moveset), 
and additionally for non-subscribed sets (setdroptable/setaddtable).

- Joining a cluster (i.e. adding a new active node to a cluster) doesn't 
need schema creation scripts, because it is extracted from an existing node.

- same for node upgrade: function definitions are extracted from another 
node.

- TABLE ADD KEY isn't implemented; pgAdmin encourages users to define 
clean PKs anyway.

- table triggers are maintained integrated in table dialogs.

A win32 binary snapshot is uploaded, linux binaries will be build tonight.

Anybody interested, please check it out, feedback welcome.

Andreas
