I have done the testing as per issue reported and below is result of same.

Configuration
----------------------
logging_collector = on 
log_directory = 'pg_log' 
log_filename = 'postgresql-%H.log' 
log_truncate_on_rotation = on   
log_rotation_age = 1h 
log_rotation_size = 0 

Behavior without the fix 
--------------------------------
   1. Problem was that on first time rotation syslogger was appending data. 

Behavior After the Patch
--------------------------------
   1. Startup time file should be appended.  -- working fine 
   2. On first rotation it should truncate the log file -- working fine
