Dear Adrian,
I appreciate your reply. Your reply gave me a new idea,
it should not be the problem that the lower() function causes the unique index
to fail.
I checked the postgresql.conf file and found that shared_buffers, work_mem and
maintenance_work_mem are default value,
but in the

Hi,

Apparently just leaving it alone until tomorrow managed to finish
creating/dropping the index. Thank you all very much.

Going through the code, it looks like they're independent, but this isn't a

Yes, pgbackrest seems the best solution for faster backup and restore.
We can close the discussion here for now, replaying million WAL files is
just slow and this is normal.

Dear Adrian,

No, I did not run ANALYZE on the 12.5 server after restoring the data.

Hi lists,
I have an index anomaly on a table; getting the error as subject.
dumping queries behind \dS+ of a table, got 4 queries (see detail below)
1st query --> OK
2nd query --> OK
3rd query ERROR same as subject (ERROR: catalog is missing 3 attribute(s)

Dear Tom,
Thanks for your reply.
Please refer to the information below：
PostgreSQL 8.2
[root@PostgreSQL8 ~]# cat /etc/redhat-release
CentOS release 6.6 (Final)
[root@PostgreSQL8 ~]# locale | grep LANG
LANG=ja_JP.UTF-8
PostgreSQL 12.5
Sorry for top posting, from phone.
But pgbackrest exactly helped with that. With compression and parallel
process in backup, the backup and restore was quick. I used this, where I
took a backup and immediately did a restore so less wals to replay, else
wal replay is indeed slow.

Sure. There is a thing called tablespace, which is basically, directory
where files for db objects reside.

Thank you, people. The big problem in my case, which I have not mentioned,
is that I think the network is a bottleneck, because I am running
pg_basebackup through internet from local country to Amazon instance in
Germany and the speed in copying is around 50 MB/sec max, that is why it
takes 2 days
I just did a backup and restore of a replica using pgbackrest.
db size 28tb
nvme/ssd storage
96 cpu, 380 gb mem
zst compression, 24 workers (backup, 12 workers restore)
2.5 hours to backup
