I added the CREATE INDEX statement in the below citext regression
tests, since it seemed to have been omitted by accident:
-- Test aggregate functions and sort ordering
CREATE TEMP TABLE srt (
name CITEXT
);
INSERT INTO srt (name)
VALUES ('aardvark'),
('AAA'),
('aba'),
('ABC'),
('abd');
CREATE INDEX srt_name ON srt (name);
-- Check the min() and max() aggregates, with and without index.
set enable_seqscan = off;
SELECT MIN(name) AS "AAA" FROM srt;
SELECT MAX(name) AS abd FROM srt;
reset enable_seqscan;
set enable_indexscan = off;
SELECT MIN(name) AS "AAA" FROM srt;
SELECT MAX(name) AS abd FROM srt;
reset enable_indexscan;
-- Check sorting likewise
set enable_seqscan = off;
SELECT name FROM srt ORDER BY name;
reset enable_seqscan;
set enable_indexscan = off;
SELECT name FROM srt ORDER BY name;
reset enable_indexscan;
