Try setting write perm. in /tmp ..(chmod 777 /tmp).
'postgres' user needs to do the write.

ERROR: could not create server file "/tmp/sss.txt": Permission denied

please tell me what may be the problem.Any permissions i have to change?
Where to modify inorder to perform successful operation.
I am in root permission only.....Though it is not working.
