With the popen patch, I expect it could be defined as '|gzip >
myfile.gz'..  I believe that patch did that.  It'd be ideal to add
support for that to file_fdw also, certainly.  That shouldn't be hard as
file_fdw is essentially a wrapper around backend COPY already and this
would just be adding a few additional options to pass through.
