test=# create extension citext;
CREATE EXTENSION
test=*# create table emp (eid int, ename citext);
CREATE TABLE
test=*# insert into emp values (1, 'aaa');
INSERT 0 1
test=*# insert into emp values (2, 'AAA');
INSERT 0 1
test=*# select * from emp where ename = 'aaa';
eid | ename
-----+-------
1 | aaa
2 | AAA
(2 rows)
Ummm... Will it use an index (a BTree index)?
