Обсуждение: Simple Query Doesn't Even with Data

I have a simple database with table, "map_table", and coulmn,
"company_letters".  The database is populated and the first row
contains a value of 'abcdefg' in the company_letters column.

If I do a select * without a where clause I get the expected results. 
However, when I execute the following select statement I was astonished
to see no results come back.  

Any idea what could possibly be wrong here?  

I've verified the data a 100 times and am totally perplexed.  Thanks.

SELECT *
FROM public.map_table
WHERE company_letters = 'abcdefg';

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.
