To use COPY instead of insert during executeBatch would require some
complicated parsing of the statement to determine if it was really a
simple insert that could be translated into COPY.  If your statement had a
function call or a subselect it could not use COPY.  Also I'm not sure
what translating an INSERT into a COPY would do if you we're inserting
into a table that had rules on it.

There was a patch around that provided an API to use COPY explicitly which
might suit your needs.
