Something removed a table.  That's what that error message means.  I can
think of a couple possibilities:

1.  Somewhere, your application or some person got in and removed (or maybe
renamed and re-created) a table that was referenced by _something_ that was
still open.

2.  Slony was dropped from the node without some set of your connections
having disconnected, and they're still expecting the triggers they can still
see to be able to write into that table.

I am by no means willing to dismiss the suggestion that there are bugs in
Slony; but this still looks to me very much like there's something we don't
know about what happened, that explains the errors you're seeing.
