How to resolve an error related to pg_dump?

532 Asked by DanielBAKER in SQL Server , Asked on Sep 29, 2022

I'm trying to restore a dump without having the appropriate roles on the receiving database.

As mentioned here but also here, you need to have the --no-owner as an option, either in pg_dump or pg_restore or both.

I've used the following command line to create my dump:

"C:Prrogram FilesPostgreSQL9.3binpg_dump.exe" --no-owner -Ft --dbname=postgresql://avo******:AV0******?@127.0.0.1:5432/BI_DB > K:BIbackupsortbck_%timestamp%.tar

The restoring line is as follows:

"C:Program FilesPostgreSQL9.3binpg_restore.exe" --host localhost --port 5432 --username "postgres" --dbname "BI_TEST2" --no-password  --no-owner --role=postgres --exit-on-error --verbose "D:Davobackupbck_04042017_1410.tar"

As you can see, both have the --no-owner option but eventually, I have the error below:

What terribly bugs me is the log below:

pg_restore: [programme d'archivage (db)] Erreur pendant le traitement de la TOC (« PROCESSING TOC ») :
pg_restore: [programme d'archivage (db)] Erreur à partir de l'entrée TOC 2633 ; 0 0 ACL adm avo******
pg_restore: [programme d'archivage (db)] could not execute query: ERREUR:  role « avo****** Â» does not exist

Why does it say it needs a role even if the --no-owner was specified?

Did I miss something?

I'm running on Postgres 9.3

The error occurs when pg_restore sets the ACLs : you can use --no-acl to prevent GRANT commands.

With the -Ft option in pg_dump, you can skip roles and ACLs only in pg_restore. You can also edit the catalogue with --list if you need more details.
