Re: ERROR on database index

Hi Laurenz, thanks for you reply. I do REINDEX but then the same problem
was trigger but with pg_description_o_c_o_index,

[XX002] org.postgresql.util.PSQLException: ERROR: index
"pg_description_o_c_o_index" contains unexpected zero page at block

I reindex pg_description and I don't see more problems. The system file
type is ext4 and is a cloud server.

But seeing logs I saw other problem in the same server but other database:
ERROR: invalid page in block 1478644 of relation
pg_tblspc/117936/PG_10_201707211/117939/259612

that's makes me wonder if the problem is in the filesystem, but I have 3
cloud servers with the same specification and working charge, and each
server have an incremental backup with barman.

Thanks
