ERROR: invalid oidvector data
The problem seems to be that array_recv passes back a zero-dimensional
array, *not* a 1-D array, when it observes that the input has no
elements. A zero-D array is not part of the subset of possible arrays
that we allow for oidvector.
Yeah, I just reached that conclusion too..
I'm less than convinced that this is worth fixing. oidvector is not
intended for general-purpose use anyway. What's the use-case where this
would come up?
I don't see any use case either, but I guess it would be nice to fix for
the sake of completeness.
