Re: [HACKERS] Bug in LIKE ?

Uhm.... I think the problem is a little worse:

create table a ( b varchar(32) );
insert into a values ( 'foo' );
insert into a values ( 'bar' );
insert into a values ( 'foobar' );
insert into a values ( 'foobar2' );

PostgreSQL 6.4.2

tacacs=> select * from a where b like 'foo%';
b
-------
foo
foobar
foobar2
(3 rows)

PostgreSQL 6.5beta2

tacacs=> select * from a where b like 'foo%';
b
-
(0 rows)

tacacs=> select * from a where b like '%foo';
b
---
foo
(1 row)

tacacs=> select * from a where b ~ '^foo';
b
-------
foo
foobar
foobar2
(3 rows)

Bye.
