Well, then I think we're converging on agreement that array comparison
should always take into account the number of dimensions and the axis
lengths. What seems still in question is whether to compare or ignore
the axis lower bounds.
I'd argue that ordinary equality should include the lower bounds, but
I'm willing to provide a separate operator (or whole btree opclass
if people want it) that ignores the lower bounds. We just need a name.
Maybe ~=, ~<, etc?
