Comments on 0003:

* If we commit 0003, is it a useful feature by itself or does it
require that we commit some or all of 0004-0014? Which of these need to
be in v18?

* Why does binary upgrade cause statistics to be dumped? Can you just
make pg_upgrade specify the appropriate set of flags?

* It looks like appendNamedArgument() is never called with
positional=true?

* It's pretty awkward to use an array of arrays of strings when an
array of structs might make more sense.

Jeff Davis
