Perhaps, but you'd get much more win out of batching multiple inserts
into one COPY. The overhead of parsing an INSERT command is relatively
high compared to what it actually gets done. Running two in parallel
does nothing to improve the overhead situation; and if you are after
speed, cutting the overhead is where you *must* focus your attention.
(If you just gotta have the sex appeal of parallelism, try running two
COPY operations in parallel...)
