[GENERAL] pg_restore -n sch1 : schema "sch1" does not exist

[lin]

Hi,all:
      I create a schema (sch1)  in the database of db1, and I also create a 
table sch1.t1, then I use the comand "pg_dump -d db1 -Fd -f dir1" to back up 
the database of db1; at lase  I drop the schema of sch1;   I want to restore 
the schema sch1, but when I execute the command "pg_restore  -d db1 -Fd dir1 -n 
sch1", get error, just like below.  
     I just want to test  the parameter of "-n" for pg_restore,  how can do to 
use the pg_restore correctly?


[wln@localhost test]$ pg_restore  -d db1 -Fd dir1 -n sch1
pg_restore: [archiver (db)] Error while PROCESSING TOC:
