Nit: I think this newline is helpful as it delimits the variable
declarations from the actual code.
I wonder whether we should also change the type of `i` to `size_t` while
at it, as `pq->len` is of type `size_t, as well (and further up in the
other test). It does mean that we have to add an explicit check whether
`pq->len == 0`, but that isn't all that bad.
In any case, if we want to do such a change, it should probably be in a
separate commit.

The type of `j` is wrong, as well.
Other than that this patch series looks good to me, thanks.
