the log_filename parameter must equal

當執行pgadmin III的工具->伺服器狀態時會出現the log_filename parameter must equal……
主要是設定檔的LOG FILE格式和PGADMIN III的格式不符所造成的

修改postgresql.conf
vim /var/lib/pgsql/9.1/data/postgresql.conf
修改下面log_filename的參數內容
log_filename = 'postgresql-%Y-%m-%d_%H%M%S.log'

安裝adminpack


使用locate adminpack找到檔案路徑
/usr/pgsql-9.1/share/extension/adminpack--1.0.sql


執行
su -l postgres
psql -d n5_data < /usr/pgsql-9.1/share/extension/adminpack--1.0.sql


出現Use "CREATE EXTENSION adminpack" to load this file.
在9.1的安裝方式改了，改用下面的指令，直接到資料庫中執行指令產生


psql -d n5_data 
CREATE EXTENSION adminpack


最後reload設定檔
su -l postgres
 /usr/pgsql-9.1/bin/pg_ctl reload -d /var/lib/pgsql/9.1/data/

重新開始後pgadmin iii就不會出現這個錯誤，也可以用pgadmin直接看到log內容
log檔案位置：/var/lib/pgsql/9.1/data/pg_log
