~*, case insensitiveness and national chars - Mailing list pgsql-general

Hi,

Consider the following commands:

] create database a encoding='LATIN2';
] \connect a
] create table a (a character(1));
] insert into a values(chr(161));
] insert into a values(chr(177));
] select count(a) from a where a ~* chr(161);

On PostgreSQL 7.3.2 this returns 2 (which is correct, since chr(161) and
chr(177) are the same character in LATIN2, just different case), but on
postgresql 7.2.2, this returns 1.

This suggests that the behavior of 7.2.2 is a bug, and something was
fixed between those two versions. Could someone point me at relevant
source file so that I can correct this in 7.2.2 (since unfortunately I
can't just upgrade to 7.3.2 now).

regards,

Marcin
