Hi,
I have a question about the UNIQUE constraint. The documentation
describes this example:
CREATE TABLE example (
a integer,
b integer,
c integer,
UNIQUE (a, c)
);

I have a table with fields:
id A B C D E F
where id is an int4 primary key.
In this table there is information like:
1 a1 b1 xxx xxx

trigger
on insert and update that holds the upper (or lower for you) value of
the orginal field like this:
create table "users" (
"email" varchar(255),
...
"u_email" varchar(255)
...
);
CREATE OR REPLACE FUNCTION "public"."

But if you're using a real key, it may need to change. The only reason *not*
do do it that way is performance issues with CASCADE.

With a little bit of legwork you can create an itext data type. It would
