実行SQLをログ出力

postgresql.confを修正して実行SQLをログ出力する設定をします。

# vi /var/lib/pgsql/data/postgresql.conf

下記の行を"mod" に指定

log_statement = 'mod'                   # none, ddl, mod, all

restartします。

# /etc/init.d/pgsql restart

すると[INSERT、UPDATE]のSQLが出力され、allにするとSELECT含めのログ【/var/log/postgresql.log】が出力されます。

select文を出したい場合

log_statement = 'all'   
log_min_duration_statement = 0

※log_min_duration_statementはスロークエリを本来検出するもので、200msなどが設定されてると思います。
