the bad news is, this generally indicates a hardware problem caused disk
data to be corrupted. this could be a memory error corrupting cache,
or the disk channel or drive. Or, it could be a issue with the OS file
system, failing under heavy concurrent random writes. Or it could
be a rare bug in postgres, but I've not heard of any block corruptions
in a long long time.
the good news is, its an index, and you can just reindex that table.
thats a system table. as the postgres user,
reindex index pg_depend_depender_index;
