The error message indicates that the _trusted schema doesn't exist, so
that the database being accessed does not contain any of the Slony-I
configuration tables.

I can see two ways for that to be the case after you had replication
"working":

1.  Is it possible that the slon process is connecting to the wrong
database?  Perhaps there are environment variables (PGHOST, PGPORT,
PGDATABASE, ...) set that are redirecting the slon to the wrong place.

You might turn connection logging on on your favorite databases, and start
up the slon; if there's a connection to a WRONG place, that'll help
diagnose what's up.

2.  The other possibility is that someone dropped the _trusted schema.

That destroys the node, as far as Slony-I is concerned...

The only way Slony-I would do this is if you submit either a DROP NODE or
UNINSTALL NODE request via a slonik script...
