That overstates things a tad; I think it's worth elaborating on a bit.

There's a problem with the results of dumping the _schema_ from a
Slony-I 'subscriber' node; you want to get the schema from the origin
node.  The problem has to do with triggers; Slony-I suppresses RI
triggers and such like on subscriber nodes in a fashion that leaves
the dumped schema a bit broken with regard to triggers.

But there's nothing wrong with the idea of using "pg_dump --data-only"
against a subscriber node to get you the data without putting a load
on the origin.  And then pulling the schema from the origin, which
oughtn't be terribly expensive there.
