我的代码太简单了，我只调用了连接字符串，仅此而已

posts.component.ts

import { Component, OnInit, Input } from '@angular/core';
import { DataService } from '../data.service';
import { Observable } from 'rxjs';
import { Sequelize } from 'sequelize';

const sequelize = new Sequelize('postgres://postgres:1@localhost:3000/test1');


@Component({
  selector: 'app-posts',
  templateUrl: './posts.component.html',
  styleUrls: ['./posts.component.css']
})
export class PostsComponent implements OnInit {

  constructor() { }

  ngOnInit(): void {

  }

}

请指出是什么问题？

Sequelize 适用于服务器端，不适用于客户端。您应该从 Nodejs 后端使用它。
