The set of functions in PQcommMethods doesn't seem clean. They
are choosed arbitrary just so that other pq_* functions used in
parallel workers will work as expected. I suppose that it needs
some refactoring.

By the way, pq_start/endcopyout() are used only in FE protocols
below 3.0, which had already bacome obsolete as of PG7.4. While
the next dev cycle is for PG10, if there is no particular reason
to support such acient protocols, removing them would make things
easier and cleaner.
