I'm kind of down on it, because it's inevitably going to add
processing overhead to every COPY operation whether the feature
is used or not.  I don't find it likely to be sufficiently
useful to justify that universal cost.

COPY is not a general-purpose filter or ETL tool, and we try
to make it one at our peril.
