Plugin command to move a backup file from the remote storage system.
<plugin_executable> restore_file <plugin_config_file> <file_to_restore>
gprestore invokes the
restore_file plugin command on the master and each segment host for the file that
gprestore will read from a backup directory on local disk.
restore_file command should process and move the file from the remote storage system to
file_to_restore on the local host.
restore_file command must exit with a value of 0 on success, non-zero if an error occurs. In the case of a non-zero exit code,
gprestore displays the contents of
stderr to the user.
