Postgres csv logging

I am trying to log executed queries into a csv file.

My main objective is to log the command tag and query. For that I enabled
logging in the postgresql.conf, my configs are the following:

#------------------------------------------------------------------------------
# ERROR REPORTING AND LOGGING
#------------------------------------------------------------------------------

# - Where to Log -

log_destination = 'stderr,csvlog'               # Valid values are
combinations of
                                        # stderr, csvlog, syslog, and
eventlog,
                                        # depending on platform.  csvlog
                                        # requires logging_collector to be
on.

# This is used when logging to stderr:
logging_collector = on                  # Enable capturing of stderr and
csvlog
                                        # into log files. Required to be on
for
                                        # csvlogs.
                                        # (change requires restart)

# These are only used if logging_collector is on:
log_directory = 'pg_log'                # directory where log files are
written,
                                        # can be absolute or relative to
PGDATA
log_filename = 'postgresql-%a-%H-%M.log'        # log file name pattern,
                                        # can include strftime() escapes
#log_file_mode = 0600                   # creation mode for log files,
                                        # begin with 0 to use octal notation
log_truncate_on_rotation = on           # If on, an existing log file with
the
                                        # same name as the new log file will
be
                                        # truncated rather than appended to.
                                        # But such truncation only occurs on
                                        # time-driven rotation, not on
restarts
                                        # or size-driven rotation.  Default
is
                                        # off, meaning append to existing
files
                                        # in all cases.
log_rotation_age = 10                   # Automatic rotation of logfiles
will
                                        # happen after that time.  0
disables.
log_rotation_size = 10240                       # Automatic rotation of
logfiles will
                                        # happen after that much log output.
                                        # 0 disables.

# These are relevant when logging to syslog:
#syslog_facility = 'LOCAL0'
#syslog_ident = 'postgres'

# This is only relevant when logging to eventlog (win32):
#event_source = 'PostgreSQL'

# - When to Log -

#client_min_messages = log              # values in order of decreasing

                                        #   %l = session line number
                                        #   %s = session start timestamp

                                        #   %x = transaction ID (0 if none)
                                        #   %q = stop here in non-session
                                        #        processes

#log_temp_files = -1                    # log temporary files equal or
larger
                                        # than the specified size in
kilobytes;
                                        # -1 disables, 0 logs all temp files
log_timezone = 'UTC'
So, the main things I did:

add csvlog to log_destination;
enable logging_collector;
set log_min_duration_statement to 0 (to log all executed queries);
enable log_connections and log_disconnections;
set log_error_verbosity to verbose (to get the max fields in the csv logs)
set log_statement to all
Yet, when I run a simple query, like:

 SELECT * FROM tests WHERE id='70';
I get:

Why is the first line, that has the query executed, saying that the command
tag is "idle", shouldn't it say "SELECT"? Is there any way to have a logged
line indicating the correct command tag and query in the proper columns? I
set the log_error_verbosity to verbose in order to get that information. Is
there any way to achieve what I want?

My postgres version is 9.4.

Thank you.
