Looking at that, I can see that Peter has added a few tests to test
the predictability of plans generated with non-hashable types, and
that these are based on money.  See 6dd8b0080787.

One possible pick to replace money for these tests is tsvector, that
cannot be hashed and has an equality operator.  Perhaps these had
better be replaced anyway?
