I was trying to update some models on sequelize and when I would run the program sequelize.sync would throw an error




error: duplicate key value violates unique constraint "pg_type_typname_nsp_index"




and




'Key (typname, typnamespace)=(person_id_seq, 2200) already exists.'




I closed out of my postgres connection through pgadmin4 and reran the script and it successfully updated/created my model definitions.



I dropped the tables and tried recreating them and sure enough it would fail everytime I had more than 1 connection.



I am only using a postgres instance on heroku with the hobby plan, so I'm not sure if the limitation lies with that



Models:



db.Person = sequelize.define('person', 
id:
type: Sequelize.BIGINT,
primaryKey: true,
autoIncrement: true,
allowNull: false
,
first_name:
type: Sequelize.STRING,
allowNull: false
,
last_name:
type: Sequelize.STRING,
allowNull: false
,
email:
type: Sequelize.STRING,
unique: true,
allowNull: false
,
passwordHash:
type: Sequelize.TEXT,
allowNull: false

,

underscored: true,
freezeTableName: true
);

db.Ingredient = sequelize.define('ingredient',
id:
type: Sequelize.BIGINT,
primaryKey: true,
autoIncrement: true,
allowNull: false,
,
name:
type: Sequelize.TEXT,
allowNull: false

,

underscored: true,
freezeTableName: true
);

db.PersonIngredient = sequelize.define('person_ingredient',
id:
type: Sequelize.BIGINT,
primaryKey: true,
autoIncrement: true,
allowNull: false
,
custom_ingredient:
type: Sequelize.TEXT

,

underscored: true,
freezeTableName: true
);
