It looks like an index corruption, a REINDEX of that table should fix the
problem.

Did you update your system recently, which
may have updated your libc/libicu version, or replicated data over different OS
version (which could lead to the same problem)?  If yes, it's a known problem
and you have to reindex all indexes that uses collatable datatypes afterwards.

You can look at https://wiki.postgresql.org/wiki/Locale_data_changes for more
details about that problem.
