Hi,
I have problem with postgresql-9.3 in our clients. They suddenly lost
power connection and all servers halt.. I repiar xfs filesystem on
CentOS7 postgresql partition. Now when I want run reindex database I
receive error:
reindexdb -d ex200
NOTICE: table "pg_catalog.pg_class" was reindexed
reindexdb: reindexing of database "ex200" failed: ERROR: invalid page
in block 101 of relation base/157934/12685
I want to try run dump and save database on plaintext but when I start
pg_dump it's hang...
pg_dump -a -v -d ex200 > ex200.sql
pg_dump: last built-in OID is 16383
pg_dump: reading extensions
pg_dump: identifying extension members
pg_dump: reading schemas
pg_dump: reading user-defined tables
pg_dump: reading user-defined functions
Any ideas what can I do.. Client told me they have a backup from 2
montgs ago....

That all looks like data corruption.
PostgreSQL should survive a crash just fine; it seems like your databases
are running with unsafe storage (that doesn't honor fsync).
If the backup from 2 months ago is a physical backup and you have WAL archives,
you can simply recover up to now.
If it is just a pg_dump, then you can either live with 2 months of data loss
or you hire professionaly that might be able to get some of your data back.
If you go for the second option, take a copy of the broken database
before doing anything else with it.
Yours,
Laurenz Albe

What object does 157934/12685 refer to? Maybe you can drop that one thing
and then recreate it.
