I have tried changing the datastore settings, trying both localhost and remote deployment, username and password, changing roles, database privileges. But nothing seem to fix this.

Am i missing something?

   adapter: 'sails-postgresql',
   url: 'postgresql://postgres:postgres@localhost:5432/postgres',

A model type :

module.exports = {
    tableName: 'roles',
    attributes: {
        name: {
            type: "string",
            required: true,
            columnType: "varchar(255) COLLATE utf8_unicode_ci NOT NULL"
        },
        company_id: {
            type: "number",
            required: true,
            columnType: "int(11) NOT NULL"
        },
        mobile_user: {
            type: "number",
            required: false,
            defaultsTo: 0,
            columnType: "tinyint(1) NOT NULL DEFAULT '0'"
        },
        enforcement: {
            type: "number",
            required: false,
            defaultsTo: 0,
            columnType: "tinyint(1) NOT NULL DEFAULT '0'"
        },
    }
};

I am migrating my db from mysql to postgre. Anyone faced same issue?

Answer 1

After experimenting with more settings and changes. I found that the issue was caused by Models, ie By changing all datatypes and conditions mentioned in columnType of a model from MySQL to PostgresSQL, it worked like a charm.

Example : tinyint(1) -> smallint, removing COLLATE condition etc
