Then a new amcheck will tell us about these duplicates. It's pity but testing can not be done automatically, as it needs a core recompile. For testing I'd recommend a protocol similar to the following:

Thanks Pavel and Anastasia for working on this!

Updating pg_catalog directly is ugly, but the following seems a simpler way to set up a regression test than having to recompile.  What do you think?

Very nice idea, thanks!

I've made a regression test based on it. PFA v.2 of a patch. Now it doesn't need anything external for testing.
