Please don't lose me here. Did I do something wrong? Isn't oid 0 used for
opaque return types? What should an opaque function return in C? I don't
see a good reason from a practical point of view to disallow opaque
functions as triggers, for this very reason, achieving none-database side
effects. At least the create trigger command should say something if it
doesn't like it.
If you have to tailor functionality around the regression tests, this is
not the right direction. After all 0 is a valid oid in this context: it's
opaque.
