Ich verwende ArchLinux
und PostgreSQL
9.4.4 und habe die Protokollierung in der Konfigurationsdatei aktiviert:
$ sudo egrep -v "^[[:blank:]]*($|#|//|/\*| \*|\*/)" /var/lib/postgres/data/postgresql.conf
max_connections = 1024 # (change requires restart)
shared_buffers = 128MB # min 128kB
dynamic_shared_memory_type = posix # the default is the first option
logging_collector = on # Enable capturing of stderr and csvlog
log_directory = '/tmp' # directory where log files are written,
log_filename = 'postgresql-%Y-%m-%d_%H%M%S.log' # log file name pattern,
log_file_mode = 0644 # creation mode for log files,
log_error_verbosity = verbose # terse, default, or verbose messages
log_statement = 'all' # none, ddl, mod, all
log_timezone = 'Asia/Jakarta'
datestyle = 'iso, dmy'
timezone = 'Asia/Jakarta'
lc_messages = 'en_CA.UTF-8' # locale for system error message
lc_monetary = 'en_CA.UTF-8' # locale for monetary formatting
lc_numeric = 'en_CA.UTF-8' # locale for number formatting
lc_time = 'en_CA.UTF-8' # locale for time formatting
default_text_search_config = 'pg_catalog.english'
Starten Sie dann den Dienst neu oder laden Sie ihn neu:
sudo systemctl restart postgresql
sudo systemctl reload postgresql
die geladenen Einstellungen:
postgres=# SELECT name, setting FROM pg_settings WHERE name LIKE '%log%';

Verwendung:
$ df | grep /tmp

Ich mache eine Abfrage psql
, aber die wird /tmp/postgresql-*
immer noch nicht angezeigt. Was kann ich tun, um herauszufinden, welches Teil die Erstellung eines Protokolls verhindert?
