Short Description
The ignored "_" character

Long Description
Hi,

I am Laszlo from Hungary.
I have some problem with PostgreSQL.

Environment:
PostgreSQL version: 7.0.3
Server OS: RedHat 5.2 , Linux-Mandrake 7.2
Client OS: RedHat 5.2 , Windows NT (pgAdmin) , Linux-Mandrake 7.2

The problem:
I create some users in database and then want to list them.
The "_" character is ignored in query statement.
The query: "select usename from pg_user where usename Like '%_u%' ;"
produces the same result as the query:
"select usename from pg_user where usename Like '%u%' ;"



Sample Code
/* Create users... */
create user i_adminuser  with sysid 40 password 'adminuser' createdb createuser ;
create user i_login      with sysid 41 PASSWORD 'login';
create user i_lekerdezo1 with sysid 45 password 'lekerdezo1';
create user i_ugyintezo1 with sysid 46 password 'ugyintezo1' createuser ;

/* The query 1: */
select usename from pg_user where usename Like '%_u%' ;

/* The Result: */
   usename
--------------
 i_adminuser
 i_ugyintezo1
(2 rows)

/* The query 2: */
select usename from pg_user where usename Like '%u%' ;

/* The Result: */
   usename
--------------
 i_adminuser
 i_ugyintezo1
(2 rows)
