当我试图在我的模式中列出关于表boarding_passes的信息时，我得到了一个错误：
demo=# d boarding_passes
Did not find any relation named "boarding_passes".
以下是我的模式中所有关系的列表：
demo=# dt bookings.*
List of relations
Schema | Name | Type | Owner

bookings | aircrafts | table | dba
bookings | airports | table | dba
bookings | boarding_passes | table | dba
bookings | bookings | table | dba
bookings | flights | table | dba
bookings | seats | table | dba
bookings | ticket_flights | table | dba

由于bookings显然不在search_path上，因此需要使用
d bookings.boarding_passes
