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....
