knex migration:latest cannot connect while psql works fine

I need help figuring out why I can't run knex migration on my local machine using. It seems that knex has some trouble connecting to the postgres database. Running knex migration:latest in the terminal gives me this error:

⇒  knex migrate:latest
Using environment: development
Error: Unable to acquire a connection
at Client_PG.acquireConnection (/Users/moldot/prjx-albert/server/node_modules/knex/lib/client.js:332:40)
at Runner.ensureConnection (/Users/moldot/prjx-albert/server/node_modules/knex/lib/runner.js:233:24)
at Runner.run (/Users/moldot/prjx-albert/server/node_modules/knex/lib/runner.js:47:42)

at Migrator._listCompleted (/Users/moldot/prjx-albert/server/node_modules/knex/lib/migrate/index.js:405:17)

I'm using postgres on my local Macbook. This is my knexfile:

var PostgressConnectionStringParser = require('pg-connection-string');

module.exports = {
  heroku: {
    client: 'pg',
    connection: process.env.DATABASE_URL,
    migrations: {
      directory: "migrations",
      tableName: "migrations",
    },
  },
  development: {
    client: "pg",
    host: "localhost",
    port: 5432,
    username: "moldot",
    database: "c_dev",
    migrations: {
      directory: "migrations",
      tableName: "migrations",
    },
    ssl: true,
  },
}

Running psql works fine:

⇒  psql -h localhost -p 5432 -U moldot -d c_dev
psql (10.1, server 9.5.4)
Type "help" for help.

c_dev=#

I'm running the command in the same directory that knexfile.js is in. Thank you!

Your knexfile has an invalid syntax. You have not given the connection attribute there.

It should look like this:

module.exports = {
  heroku: {
    client: 'pg',
    connection: process.env.DATABASE_URL,
    migrations: {
      directory: "migrations",
      tableName: "migrations"
    }
  },
  development: {
    client: "pg",
    connection: {
      host: "localhost",
      port: 5432,
      username: "moldot",
      database: "c_dev",
    },
    migrations: {
      directory: "migrations",
      tableName: "migrations"
    }
  }
}
