i have problem in database encoding with indexing
case :1
when i initdb -E win874 mydb and create database with createdb -E win874
dbname
and create table emp with index in empname field
i can select sorting name correct in thai alphabet
such select empName from emp order by empName;
but in
select empName from emp where empname like 'xxx%'
it not using index scan , it use seq scan so it may slow in find name
case :2
when i initdb mydb (use default) and create database with createdb -E win874
dbname
and create table emp with index in empname field
i can not select sorting name correct in thai alphabet
but in
select empName from emp where empname like 'xxx%'
it using index scan , very fast in find name
problem:
how can i configure database that can correct in sorting name and using
index scan in like 'xxxx%' search
using FreeBSD 5.4
postgreql 8.0.
