O que está tentando executar?
Parece que você está recriando as tabelas.

vou dar uma olhada na classe de tabelas

Acho que é alguma coisa errada no hibernate cfg

<?xml version="1.0" encoding="UTF-8"?>

ou na conexao do hibernate util update era pra dar update

package com.meson.sistemavendas.util;

}

public static Connection getConexao(){
	Session sessao = fabricaDeSessoes.openSession();
	
	Connection conexao = sessao.doReturningWork(new ReturningWork<Connection>() {
		@Override
		public Connection execute(Connection conn) throws SQLException {
			return conn;
		}
	});
	
	return conexao;
}

private static SessionFactory criarFabricaDeSessoes() {
	try {
		Configuration configuracao = new Configuration().configure();
                    configuracao.addAnnotatedClass(Estado.class);
                  configuracao.addAnnotatedClass(Cidade.class);
		
		ServiceRegistry registro = new StandardServiceRegistryBuilder().applySettings(configuracao.getProperties()).build();
		
		SessionFactory fabrica = configuracao.buildSessionFactory(registro);
		
		return fabrica;
	} catch (Throwable ex) {
		System.err.println("A fábrica de sessões não pode ser criada." + ex);
		throw new ExceptionInInitializerError(ex);
	}
}

}

A propriedade hibernate.hbm2ddl.auto, configurada como update, não deveria tentar recriar tabelas já existentes.
A criação de tabelas só é invocada na inicialização do hibernate.
Ou seja, você, por alguma razão, está invocando a criação da estrutura do hibernate mais de uma vez.

o update era para atualizar a tabela vou postar o domain as vezes é algum erro la

mas por via das dúvidas vou recriar o hibernate.cfg com outro codigo que vi aqui
