Well, if you can provide the pgbadger command line you are using and some lines of your log we could help.

Sorry for the inconvenient.
The issue form that i'm french and seems taht as the 'lc_messages is "fr_FR", pg_bader can't parse the file.
I have modify 2 lines in conf files:
log_line_prefix = '%t [%p]: '
lc_messages = 'C'
With line :
pgbadger -v -p '%t [%p]: ' /var/log/postgresql/postgresql-15-main.log
And its work !!
