This error message is from postgresql, unrelated to a specific feature/table/etc
of ovirt.

It most likely means you had some corruption in your database, either due to
bad hardware (RAM, disk, etc) or temporary issues (power failure, kernel panic

If you think it was a temporary issue and just want to fix this specific bad
index, you can recreate it with the command "reindex". Search for e.g.
'postgresql "ignore_system_indexes" reindex' to find more relevant information.
