Обсуждение: Test for char errors
I downloaded psotgresql-9.4.4 source code and build it on Centos 6.5 x64 edition. Then I run 'make test' and it reported that 'All 145 tests passed'. But the expected output and actual output of test 'char' are not same.
The expected output of in 'src/test/regress/expected/char.out' is:SELECT '' AS five, c.*
FROM CHAR_TBL c
WHERE c.f1 < 'a';
five | f1
------+----
| A
| 1
| 2
| 3
|
(5 rows)
SELECT '' AS five, c.*
FROM CHAR_TBL c
WHERE c.f1 < 'a';
five | f1
------+----
| 1
| 2
| 3
|
(4 rows)

In the case of char, there is not only char.out, but as well char_1.out and char_2.out. In your case char_1.out seems to match. -- Michael

Thanks Michael! Could you tell me which option determines what expected output is used?

Some tests have multiple expected outputs. In the case of char, there
is not only char.out, but as well char_1.out and char_2.out. In your
case char_1.out seems to match.
