hu_HU.UTF8 case insensitive search fail to return values - Mailing list pgsql-bugs

Hi<br /> I have a problem related to the encoding. Maybe this is not the right place to ask for help, in this case
pleasetell me where to ask for help.<br /><br /> database version: PostgreSQL 8.1.2 on i686-pc-linux-gnu, compiled by
GCCgcc (GCC) 3.3.5 (Debian 1:3.3.5-13)<br /><br /> The problem is the following:<br /> I have created the database with
UTF8encoding (createdb -O postgres -E UTF8 dbname). The database uses the following encodings/locales:<br /><font
size="3"><fontcolor="#000000">lc_collate | hu_HU.UTF8 | Shows the collation order locale. <br /> lc_ctype | hu_HU.UTF8
|Shows the character classification and case conversion locale. <br /> lc_messages | C | Sets the language in which
messagesare displayed. <br /> lc_monetary | C | Sets the locale for formatting monetary amounts. <br /> lc_numeric | C
|Sets the locale for formatting numbers. <br /> lc_time | C | Sets the locale for formatting date and time values.<br
/><br/> Lats say we have a table named some_table with the following datas:<br /> create table some_table(id integer,
strvarchar(100));<br /><br /> insert into some_table values(1, 'alma a fa alatt');<br /></font></font><font
size="3"><fontcolor="#000000">insert into some_table values(2, 'nyári piros alma');<br /></font></font><font
size="3"><fontcolor="#000000">insert into some_table values(3, 'ez egy állomány');<br /></font></font><font
size="3"><fontcolor="#000000">insert into some_table values(4, 'egy másik ÁLLOMÁNY');</font></font><br /><font
size="3"><fontcolor="#000000"><br /> (note that I used a acute and A acute intentionally; these are some Hungarian, not
toomeaningful words)<br /><br /> When I execute the following query, the following results are returned:<br /><br />
