Is that the actual error message? The closest string I can find in 8.3
or HEAD is "index operators must return boolean".

It seems possible that you could get an error like that as a result of
something creating a shell operator and not filling it in afterwards,
but if so I'd blame the earlier something; the worst that can be laid at
CREATE OPERATOR CLASS's door is giving a less helpful error message than
it could. We really need to see a complete example of how to reproduce
the problem before speculating about appropriate fixes.
