Hi!
It not works. :(
I try it:
proba=# create table "tabla1" ("ID" int8 NOT NULL UNIQUE, "nev" varchar(20) );
NOTICE: CREATE TABLE/UNIQUE will create implicit index 'tabla1_ID_key' for
table 'tabla1'
CREATE
proba=# create table "tabla2" ("ID2" int8 NOT NULL UNIQUE, "nev2" varchar(20) );
NOTICE: CREATE TABLE/UNIQUE will create implicit index 'tabla2_ID2_key' for
table 'tabla2'
CREATE
proba=# alter table tabla1 drop constraint ID not null;
ERROR: parser: parse error at or near "not"

What is the problem?
