Hello,
This is PostgreSQL v10.10 64Bit, running on Windows 10 64Bit.
One user, by himself, without asking for help, cloned his OS from one disk to
Hyper-V disk. Old disk was not accessed, OS was shutdown while he is doing the
cloning. He used some kind of tool that I do not know for that purpose. New
server is running under Hyper-V.
Once he saw Hyper-V server is up and running he deleted old disk for good.
Unfortunately, new system has more than brief problems. He has no backup of the
database cluster or particular database(s) in it.
I see in log following errors:
2020-07-16 12:28:17.598 +03 [3964] HATA (ERROR): "pg_opclass_oid_index"

Basic translation to English is:
ERROR: "pg_opclass_oid_index" index 0 block unexpected empty page
HINT:Please REINDEX it.
LOG: cannot read fata from client: unrecognized winsock error 10054
FATAL: base/16394/2684 object 0 block invalid page
When I try to connect server on command line using psql I get same error:
PS C:\Program Files\PostgreSQL\10 - Kopya\bin> .\psql.exe -U postgres
psql: ÖLÜMCÜL (FATAL): "pg_opclass_oid_index" indeksinde 0 bloğunda
beklenmeyen boş sayfa
İPUCU: Lütfen onu REINDEX'leyin.
PS C:\Program Files\PostgreSQL\10 - Kopya\bin> .\psql.exe -U postgres -h

psql: ÖLÜMCÜL (FATAL): "pg_opclass_oid_index" indeksinde 0 bloğunda

İPUCU: Lütfen onu REINDEX'leyin.
I am told that some databases in cluster can be accessed, not all. They are
accessed from an application and not by admin tools. I do not know how many
databases exists in the cluster or their names.
I have tried to dump everything and that also failed:
PS C:\logs> & 'C:\Program Files\PostgreSQL\10 - Kopya\bin\pg_dumpall.exe' -f
dump.bak -U postgres
pg_dump: [arşivleyici (db)] sorgu başarısız oldu: HATA (ERROR):
base/16394/2684 nesnesinin 0 bloğunda geçersiz sayfa
pg_dump: [arşivleyici (db)] sorgu şu idi: SELECT
pg_catalog.set_config('search_path', '', false)
pg_dumpall: pg_dump "ZEntegre" veritabanında başarısız oldu, çıkılıyor
I wonder if there is anything that can be done here.
Thanks & Regards,
Ertan
