ubuntu下postgresql的pg_log目錄？

Question

我也跟着上http://pydanny-event-notes.readthedocs.org/en/latest/DjangoConEurope2012/10-steps-to-better-postgresql-performance.html

它說，設置log_directory = pg_log

哪來Ubuntu的那個目錄指令？ :(

Answer 1

在Postgres的數據目錄類似/var/lib/postgresql/9.3/main/pg_log

Answer 2

select format('%s/%s', 
    current_setting('data_directory'), 
    current_setting('log_directory'));
