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?
Hmm, seems -n is not the same in pg_dump and pg_restore. If you do a
dump with the
-n switch you get the SCHEMA creation in the restore. If you use the -n
on the restore
you get the contained objects but not the SCHEMA creation statement.
Might try generating a TOC from your dump and then pulling the entry for
schema
sch1 and put it at the top of the TOC you generated below.
