For once, this looks more like a problem in logical decoding, which is
trying to assert about the tuple being updated; the assertion failing is
the one added a week ago about not palloc'ing in a critical section.
Andres told me on IM that there's another weird thing going on (which is
how the catalog tuple gets a multixact in the first place) which is that
Slony does a SELECT FOR SHARE in the catalog tuple.
One simple approach would be to just disable that particular assert when
in a critical section.
