> Command utility is designed to run a shell command in hawq test. It follows below steps to run command:
> {noformat}
> Step 1: prepare the shell command string
> Step 2: run the command using popen
> Step 3: save the result of command in memory (i.e., stdio returned from popen)
> Step 4: check the status of the command (i.e., status returned from popen)
> Step 5: save the result to file if output file is specified
> {noformat}
> Now it takes about 75 sec to save the result of command in memory in step 3 if the command is to run SQL file using psql. This needs to be fixed so as to improved the performance.
