I think we're putting the cart before the horse here. I think we need a
perl module in core that can be loaded by the buildfarm code,  and could
also be used by a standalone find_typedef (c.f.
src/test/PostgreSQL/Test/AdjustUpgrade.pm). To be useful that would have
to be backported.

I'll have a go at that.
