Log, yes, unless it's a temp table. The point is we could avoid taking
buffer content locks. Come to think of it, we could implement that
trivially in the heapam.c routines; it would then apply to any table
update whether generated by COPY or otherwise.

Exactly my point; we don't have to change any syntax, so pg_dump
doesn't care.
