Re: Unexpected block ID found when reading data
Yes, i’ve found at some forums (DBeaver) that it is a bug on pg_restore. Hopefully so, so that I have hope to restore my data later. This is the output for "pg_restore —version”: pg_restore (PostgreSQL) 12.7 And this are some "pg_restore -l -v dbdump.backup” output: ; dbname: mydb ; TOC Entries: 6487 ; Compression: 3 ; Dump Version: 1.14-0 ; Format: CUSTOM ; Integer: 4 bytes ; Offset: 8 bytes ; Dumped from database version: 9.6.21 ; Dumped by pg_dump version: 12.5 Once again many thanks for the help. Really appreciate it. > On 3 Aug 2021, at 20.59, Tom Lane wrote: > > Vijaykumar Jain writes: >> On Tue, 3 Aug 2021 at 08:19, Gilar Ginanjar >> wrote: >>> I'm not sure which pg_dump version did i use before, but I used psql 12.5 >>> to dump and the db version is postgresql 9.6. >>> >>> pgrestore command: >>> pg_restore -U myuser -j8 -d mydb dbdump.backup >>> >>> I’ve tried to restore to postgre 9.6, 12.1 and 12.5 > >> 9.6 has had a lot of minor fixes all the way to 9.6.22 , I am speculating, >> maybe your restoration to the latest minor version is failing. > > This error is internal to pg_restore, so the target server version isn't > going to make any difference.

Re: Unexpected block ID found when reading data
I’m not sure which patch version i used to dump, but i was using postgre 12.5 for pg_dump back then. I’m running pg_restore -f dbdump.backup right now, I think it will take some times because it has a large size (around 9 GB). There are no issues yet.

Re: Unexpected block ID found when reading data
Hi, Luca Thanks for the response. I’ve tried with option -L and -l before. The schema is fine, but sadly when i try to restore only data on the tables i need, it comes up with the error. Is there any small chance I can view/save/restore my data? I desperately need it. Many thanks. > On 3 Aug 2021, at 17.06, Luca Ferrari wrote: > > On Tue, Aug 3, 2021 at 4:49 AM Gilar Ginanjar > wrote: >> pgrestore command: >> pg_restore -U myuser -j8 -d mydb dbdump.backup >> > > As a desparate approach I would try to use options -L and -l to > extract objects from the backup and restore a small subset of them, in > order to find out where the error is. > I suspect the compressed archived is damaged. > > Luca

Unexpected block ID found when reading data
Hi, I have a db dump (.backup) that i want to restore. But it comes up with error: "found unexpected block ID when reading data" Is there any chance i can save my backup? The problem is I don't have the database anymore. I used psql 12.5 when dumping the database approx a year ago.
