Problem Description:
--------------------
Sometimes expresion like 'select a from b where a like 'abc%';' gives
null result, while 'select a from b where a like 'abcd%';' gives
right result (several records). In some case first expression
gives some result but it doesn't contains result of the second
one... But expresion '... like 'ab%';' gives result containing
results of the first an the second.
--------------------------------------------------------------------------
Test Case:
----------
All fields I tried contain russian characters (there was some
fields with english characters but I don't find such error with them)
example:
vkuzmina=> select tit from cvcat where lower(tit) like '���������%';
tit
-----------------
��������� � �����
(1 row)
vkuzmina=> select tit from cvcat where lower(tit) like '��������%';
tit
---
(0 rows)
vkuzmina=> select tit from cvcat where lower(tit) like '�������%';
tit
-----------------
��������� � �����
(1 row)
vkuzmina=> select tit from cvcat where tit like '�������%';
tit
-----------------
��������� � �����
(1 row)
vkuzmina=> select tit from cvcat where tit like '��������%';
tit
---
(0 rows)
vkuzmina=> select tit from cvcat where tit like '���������%';
tit
-----------------
��������� � �����
(1 row)
