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.
