[GENERAL] Postgres 9.6.2 and pg_log

Good day all,

I just noticed an anomaly regarding the logging. I have my logging set up as follows:

log_filename = 'postgresql-%d.log'

log_truncate_on_rotation = on

My log file postgresql-21.log contains only entries for today (April 24). When I restart the service, entries correctly start accumulating in postgresql-24.log.  For example, my postgresql-21.log contains:

2017-04-24 11:19:34 EDT LOG:  received fast shutdown request

2017-04-24 11:19:34 EDT LOG:  aborting any active transactions

2017-04-24 11:19:34 EDT LOG:  autovacuum launcher shutting down

2017-04-24 11:19:35 EDT LOG:  shutting down

2017-04-24 11:19:35 EDT LOG:  database system is shut down

My postgresql-24.log contains:

2017-04-24 11:19:40 EDT LOG:  database system was shut down at 2017-04-24 11:19:35 EDT

2017-04-24 11:19:40 EDT LOG:  MultiXact member wraparound protections are now enabled

2017-04-24 11:19:40 EDT LOG:  database system is ready to accept connections

2017-04-24 11:19:40 EDT LOG:  autovacuum launcher started

This is on Windows 10, 64-bit

PostgreSQL 9.2.2, compiled by Visual C++ build 1800, 64-bit

(EnterpriseDB installer)

Note that this is not a major concern on my end; postgres 9.6.2 has otherwise been running flawlessly.
