Обсуждение: 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
LIKEexpression~~  | varchar     | text        | bool      | matches LIKE expression
 

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

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

AFAIK postgres 7.0.3 does not have it, ILIKE appeared in 7.1 

But you could use the case-independant regular expressions.

There is no ILIKE function in 7.0.3.

That's odd, because it's in the 7.0.3 documentation...

Where?  A quick grep doesn't find it there anywhere.
