I didn't address this in my v6 (yet). Primarily because this isn't
related to the pg_regress changes, but rather to my change that started
using command_ok in these tests to run pg_regress. I'm thinking a bit if
we can make this nicer, one way would be to have command_ok take an
optional argument that allows disabling truncation in places where we
know the output won't be huge.
