How to get rid of notices for create table?

Hi,

I did a search for this issue but don't seem to find
anything reasonably satisfactory.

I'm getting boring notices when creating tables:

test=# CREATE TABLE cliente (
test(# id INTEGER NOT NULL,
test(# id_indica INTEGER NULL,
test(# email VARCHAR(40) NULL,
test(# contato VARCHAR(40) NULL,
test(# data DATE DEFAULT
NOW(),
test(# log VARCHAR(40) NOT NULL,
test(# num VARCHAR(16) NOT NULL,
test(# comp VARCHAR(16) NULL,
test(# bairro VARCHAR(40) NOT NULL,
test(# cep CHAR(8) NOT NULL,
test(# cidade VARCHAR(40) NOT NULL,
test(# estado CHAR(2) NOT NULL,
test(# refend VARCHAR(256) NULL,
test(# CONSTRAINT pk_cliente PRIMARY KEY (id),
test(# CONSTRAINT uk_email UNIQUE (email),
test(# CONSTRAINT ck_indica CHECK (id != id_indica)
test(# );
NOTICE: CREATE TABLE / PRIMARY KEY will create
implicit index "pk_cliente" for table "cliente"
NOTICE: CREATE TABLE / UNIQUE will create implicit
index "uk_email" for table "cliente"
CREATE TABLE

Got a few questions:

1 - What those 2 notice messages mean?
2 - How can I get rid of them?

Regards,
Scorphus.
