Update. Turns out that 8.4 DOES know how to execute the view. If you
try to group on a user-defined composite type, 8.4 just goes ahead and
groups it, rather than giving the old "could not identify an ordering
operator" error.
Which renders the whole idea of creating my own opclass for the type
very much bunk.
What sorcery is this? Does 8.4 add some kind of default ordering
strategy for composite types?
