Hmm. We should try to conclude over the benefit of TAP over
isolation, and merge both patches together if the consensus is towards
a TAP test.

The isolation test feels much cleaner to me in terms of clarity and
debugging output compared to the suggested TAP test as there are many
SQL sequences the test depends on. Other opinions?
