Coleguinha, o erro está bem transparente…
1 - verifique qual o ip q. vc colocou na String de conexao do banco
2 - Se o ip estiver correto, verifique as permissoes do psql sobre acesso externo (de outra máquina na mesma rede, de outra máquina fora da rede)
3 - se o erro persistir, poste aqui novamente…
