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
