Maybe. I'm not sure why parsing "(1,2,3,4,5)" in an EXECUTE parameter
should be faster than parsing the exact same thing in an INSERT,
though.

Of course, you still need to get it in that format. Be careful to
include any parsing you're doing to create the binary date in the
benchmarks. Inevitably, at least part of the difference will be costs
simply moving from the psql process to your own.
