I will find out some bug with like operator if I use locales.

Steps to involve a bug result:

1. Compilation
./configure --enable-locale # not needed for RPMS precompiled binaries

2. Starting postmaster
export LC_CTYPE=cs_CZ
export LC_COLLATE=cs_CZ # this setting is important for the
bug result
postmaster -S -D /home/pgsql/data -o '-Fe'

3. SQL steps
create table test (name text);
insert into test values ('á'); # the first char is E1 from LATIN 2
coding
insert into test values ('áb');
create index test_index on test (name);
set cpu_tuple_cost=1; # force backend to use index
scanning
select * from test where name like 'á%';

BUG: Only 1 line is selected with 'á' only instead of both lines.
