I'm doing DDL on a table that is NOT replicated. Are you saying I shouldn't even have unreplicated tables in the same
database?
Now I shouldn't be referencing the table from an unreplicated one, but that's what I'm trying to fix!

1) I'm dropping a foreign key, not an index. The problem is that somehow that gets translated into trying to drop the
primarykey of the _other_ table.
2) The constraint doesn't exist on the master, only the slave, so I don't beleive EXECUTE SCRIPT will work, no?

I'm not entirely convinced it's a Slony problem. Actually when I first posted I didn't even think it might be slony
related.
