Possibly what you're running into is that 7.4 is restrictive about what
you can do with an array that's NULL. Until pretty recently, assigning
to an element of a NULL array left the array still NULL --- this is an
artifact of the fact that the system sees the assignment as a binary
operation with the array and the new element as inputs.
