Well, I didn't make a general statement, I made one about this patch.
And this would add a significant bunch of untested code, and it'll likely
take years till it gets decent coverage outside.

That's a really large scope creep imo.  Adding a bunch of user-facing
psql stuff doesn't compare in complexity to running a test across
platforms.  We can just do that from regess.c or such, if that ends up
being a problem..
