Support ALTER TYPE

[gabssnake]

Feeling guilty from all the issues opened... ^^

Trying to alter types :

-- Our example table and enum type
CREATE SCHEMA humanity;
CREATE TYPE humanity.moods AS ENUM ('happy', 'ok');

-- Use your enum
CREATE TABLE human (mood humanity.moods);
INSERT INTO (mood) VALUES ('happy'), ('ok'), ('happy');

-- Error: Unexpected token "humanity"
ALTER TYPE humanity.moods ADD VALUE 'enthusiastic';

No problem :) Adding it to todo list ... i'll deal with it when I have some spare time !
