Ensure the filename pattern for log files is set correctly
LowLevel 1Manual reviewpostgres
Description
The log_filename setting specifies the filename pattern for log files. The value for log_filename should match your organization's logging policy. The value is treated as a strftime pattern, so %-escapes can be used to specify time- varying file names. The supported %-escapes are similar to those listed in the Open Group's strftime specification.
How it is checked
Audit method: Manual review
This recommendation cannot be checked automatically. A scan lists it with these instructions when you pass --include-manual.
Run SHOW log_filename; (default postgresql-%a.log, one file per weekday) and confirm the strftime pattern matches your log retention and rotation policy.
How it is fixed
Fix method: Guidance or infrastructure patch
ALTER SYSTEM SET log_filename = 'postgresql-%Y%m%d.log'; then SELECT pg_reload_conf();
