I think this is essentially a bug in the Slony library --- it ought to
provide a way to flush its internally cached plan(s).
In the longer term there may be infrastructure for automatic rebuilding
of invalidated plans, but I wouldn't hold my breath waiting for this.
(Even if it existed now, most likely the Slony code would have to change
to take advantage of it ...)
