Rails 3與Postgresql - 嘈雜的數據庫？

Question

我最近搬到我的Rails應用程序給Postgres並且在發展日誌發現它的完整的SQL語句如下所示：

SQL (1.1ms) SELECT a.attname, format_type(a.atttypid, a.atttypmod), d.adsrc, a.attnotnull 
FROM pg_attribute a LEFT JOIN pg_attrdef d 
ON a.attrelid = d.adrelid AND a.attnum = d.adnum 
WHERE a.attrelid = '"permissions"'::regclass 
AND a.attnum > 0 AND NOT a.attisdropped 
ORDER BY a.attnum 
    SQL (1.1ms) SELECT a.attname, format_type(a.atttypid, a.atttypmod), d.adsrc, a.attnotnull 
FROM pg_attribute a LEFT JOIN pg_attrdef d 
ON a.attrelid = d.adrelid AND a.attnum = d.adnum 
WHERE a.attrelid = '"spaces"'::regclass 
AND a.attnum > 0 AND NOT a.attisdropped 
ORDER BY a.attnum 

任何人都知道這筆交易是什麼這個問題，好像它是一個性能命中？是嗎？

感謝
