if gpfdist runs on a remote server, we can run gpdb on a linux
server, then run the regress test cases in this folder on the linux
server to test if the gpfdist can work well.

Now we just support gpfdist on a remote windows server.
make installcheck_win can test gpfdist of windows.
Need to export REMOTE_HOST, REMOTE_PORT, REMOTE_USER, REMOTE_KEY
COORDINATOR_DATA_DIRECTORY, PG_PORT before running these test cases.

The scripts of start_gpfdist_remote_win are used to start and stop gpfdist running on windows.

If you want to test gpfdist on another os, such as darwin, you can create a folder named
start_gpfdist_remote_darwin and add some scripts to start and stop gpfdist.
Gpfdist does not support Unix os in gpdb version 7.
