This isn't a bug; or at least, it's not plpgsql's fault. The array
variable is initially NULL, same as any other plpgsql variable you
didn't explicitly initialize. And assigning to an element of a NULL
array yields another NULL array.
Perhaps that behavior should be changed, but I think it would require
making unsupported assumptions about what the user wants...
