BUG #19025: PostgreSQL log is not rotated

The following bug has been logged on the website:

Bug reference: 19025
Logged by: José Antonio Morcillo Valenciano
Email address: jose(dot)morcillo(dot)valenciano(at)gmail(dot)com
PostgreSQL version: 16.2
Operating system: Red Hat Enterpr Linux 5.14.0-427.35.1.el9_4.x86_64
Description:

Hi folks!

We have configured our log rotating policy as follows:

logging_collector = on
log_destination = 'stderr'
log_directory = '/postgresql/16/log/cpdm-cluster86'
log_filename = 'postgresql-%Y-%m-%d_%H%M%S.log'
log_rotation_age = 1d
log_rotation_size = 250MB
log_truncate_on_rotation = on

But the log is 16GB and no rotation has happened:

[PRO] $ ls -lh
total 16G
-rw-r--r-- 1 postgres postgres 16G Aug 19 12:16
postgresql-2025-07-12_001207.log

I have been searching any bug but I could not find it. Any ideas?

Thanks!!!

Regards,
José Antonio
