wp_postmeta表时间久了，各种东东占用太多行，比如_edit_lock、_edit_last等无用的信息。

DELETE FROM wp_postmeta where meta_key like '%oembe%' DELETE FROM wp_postmeta WHERE meta_key = '_edit_lock'; DELETE FROM wp_postmeta WHERE meta_key = '_edit_last'; DELETE FROM wp_postmeta WHERE meta_key = '_wp_old_slug'; DELETE FROM wp_postmeta WHERE meta_key = '_encloseme'; DELETE FROM wp_postmeta WHERE meta_key = '_pingme'; DELETE FROM wp_postmeta WHERE meta_key = 'wp_old_date'; |
这得常清理，每隔几个月清一次
