Bug in ILIKE function?

Hi,

I have just tried using the ILIKE function in 7.0.3. I assume that it is
just a case-insensitive version of LIKE. (Please correct me if I am wrong
on this assumption.)

This is my example test case:

usa=# select 'test' LIKE '%es%';
?column?
----------
t
(1 row)

usa=# select 'test' ILIKE '%es%';
ERROR: parser: parse error at or near "ilike"
usa=#

HEre is a dump (\do) of the some of the tilde operators in 7.0.3:

~* | bpchar | text | bool | matches regex.,
case-insensitive
~* | name | text | bool | matches regex.,
case-insensitive
~* | text | text | bool | matches regex.,
case-insensitive
~* | varchar | text | bool | matches regex.,
case-insensitive
~= | box | box | bool | same as
~= | circle | circle | bool | same as
~= | point | point | bool | same as
~= | polygon | polygon | bool | same as
~= | tinterval | tinterval | bool | same as
~~ | bpchar | text | bool | matches LIKE expression
~~ | name | text | bool | matches LIKE expression
~~ | text | text | bool | matches LIKE expression
~~ | varchar | text | bool | matches LIKE expression

Notice that there's no ILIKE operators, (~~*), at all!

Is this documented, but not implemented or what????
