问题
I did backup on database on different server and that has different role than I need, with this command:
pg_dump -Fc db_name -f db_name.dump
Then I copied backup to another server where I need to restore the database, but there is no such owner that was used for that database. Let say database has owner owner1, but on different server I only have owner2 and I need to restore that database and change owner.
What I did on another server when restoring:
createdb -p 5433 -T template0 db_name
pg_restore -p 5433 --role=owner2 -d db_name db_name.dump
But when restore is run I get these errors:
pg_restore: [archiver (db)] could not execute query: ERROR: role "owner1" does not exist
How can I specify it so it would change owner? Or is it impossible?
回答1:
You should use the --no-owner option, this stops pg_restore trying to set the ownership of the objects to the original owner. Instead the objects will be owned by the user specified by --role
createdb -p 5433 -T template0 db_name
pg_restore -p 5433 --no-owner --role=owner2 -d db_name db_name.dump
