There’s two non-obvious things to know when starting to use pgbadger with AWS RDS.
log_statement = None
Don’t set this to all as the AWS docs suggest.

pgbadger about the log format that RDS insists on:
$ pgbadger -f stderr -p '%t:%r:%u@%d:[%p]:' postgres.log
Hope that saves you some time. Note that the
-f stderr is required for
pgbadger v10 and above2:
