Block indexing halting at tezos testnet. Problem with "big_map_contents_pkey" index.

[amurde]

Hello all,
yesterday morning both our conseil halted reading data from Tezos testnet.
At the same time, around 6 in the morning CET.

Error in logs is:
"
Caused by: org.postgresql.util.PSQLException: ERROR: index row size 3032 exceeds btree version 4 maximum 2704 for index "big_map_contents_pkey"
Detail: Index row references tuple (35161,12) in relation "big_map_contents".
Hint: Values larger than 1/3 of a buffer page cannot be indexed.
Consider a function index of an MD5 hash of the value, or use full text indexing

Tezos node ver 11.1

Hello all,
i dropped database on one of the nodes and tried to read it from the scratch.
