Log Message:
-----------
Reduce CPU utilisation of WALSender process. Process was using 10% CPU
doing nothing, caused by naptime specified in milliseconds yet units of
pg_usleep() parameter is microseconds. Correctly specifying units
reduces call frequency by 1000. Reduction in CPU consumption verified.
