I'm not sure what you are doing wrong, but the "postgres" user actions
should get logged just like everything else.

For grins I followed the aforementioned supplement pdf sections 2.2
(pgaudit) except I used cvslog instead of stderr as a destination, and
2.3 (logging), started up postgres, logged in as postgres, created a
table, and then tailed the postgres log:

----------------
tail -n 33 $PGDATA/postgresql.conf
shared_preload_libraries = 'pgaudit'

# Enable catalog logging - default is 'on'
pgaudit.log_catalog='on'
# Specify the verbosity of log information (INFO, NOTICE, LOG, WARNING,
DEBUG)
pgaudit.log_level='log'
# Log the parameters being passed
pgaudit.log_parameter='on'
# Log each relation (TABLE, VIEW, etc.) mentioned in a SELECT or DML
statement
pgaudit.log_relation='off'
# For every statement and substatement, log the statement and parameters
every time
pgaudit.log_statement_once='off'
# Define the master role to use for object logging
# pgaudit.role=''
# Choose the statements to log:
# READ - SELECT, COPY
# WRITE - INSERT, UPDATE, DELETE, TRUNCATE, COPY
# FUNCTION - Function Calls and DO Blocks
# ROLE - GRANT, REVOKE, CREATE/ALTER/DROP ROLE
# DDL - All DDL not included in ROLE
# MISC - DISCARD, FETCH, CHECKPOINT, VACUUM
pgaudit.log='ddl, role, read'

log_line_prefix = '%m %u %d: '
log_destination = 'csvlog'
logging_collector = on
log_directory = 'pg_log'
log_filename = 'postgresql-%a.log'
log_file_mode = 0600
log_truncate_on_rotation = on
log_rotation_age = 1d
log_rotation_size = 0
----------------

(restart postgres)

----------------
psql test
psql (11.1)
Type "help" for help.

test=# CREATE TABLE pgatest(id int);
CREATE TABLE
test=# \q

----------------
tail -n 1 $PGDATA/pg_log/postgresql-Thu.csv
2019-11-21 10:07:39.320
EST,"postgres","test",14809,"[local]",5dd6a829.39d9,1,"CREATE
