Yes.
The only case I can think of where we wouldn't want this is COPY.
BTW, this should also apply to delimiters other than commas; for example, some
geometry types use ; as a delimiter between points.
I don’t think it should apply to the internals of types, necessarily. JSON, for
example, always dies on an trailing comma, so should probably stay that way.
Well, maybe allow it on JSONB input, but not JSON. Though we perhaps don’t want
their behaviors to diverge.
The JSON spec is quite clear on this. Leading and trailing commas are
not allowed. I would fight tooth and nail not to allow it for json (and
by implication jsonb, since they use literally the same parser - in fact
we do that precisely so their input grammars can't diverge).
