findOrCreate hangs, if only one connection is available

In the example the maximum amount of conections is set to 1.

findOrCreate does not return (or maybe it will at the idle time…)

If “max:2”, then it works (giving an exception due to unique violation.

var S = require('sequelize');

var sequelize = new S('seq_test', 'passwd', '', {
    host: 'localhost',
    dialect: 'postgres',
    pool: { max: 1, 
            min: 0, idle: 10000, },
    define: {  },
});

var User = sequelize.define('User', {
    name: { type: S.STRING(50), allowNull: true, unique: true},
    pass: { type: S.STRING(50), allowNull: true},
});

sequelize.sync()
.then(function (){
    User.create({ name: 'A', pass: 'A' })
    .then(function (){
        User.findOrCreate({
          defaults: { name: 'A', pass: 'A' },
          where: { name: 'B' }
        })
        .catch(function (e){
            console.log('ERR', e);    
        })
        .then(function (){
            console.log('DONE');
            sequelize.close();
        });
    });
});
