Change Post Schema, Add some Post Services

+/*
+  Warnings:
+
+  - The primary key for the `Post` table will be changed. If it partially fails, the table could be left without primary key constraint.
+  - You are about to drop the column `content` on the `Post` table. All the data in the column will be lost.
+  - The `id` column on the `Post` table would be dropped and recreated. This will lead to data loss if there is data in the column.
+  - A unique constraint covering the columns `[id]` on the table `Post` will be added. If there are existing duplicate values, this will fail.
+  - Changed the type of `postId` on the `Comment` table. No cast exists, the column would be dropped and recreated, which cannot be done if there is data, since the column is required.
+  - Added the required column `example` to the `Post` table without a default value. This is not possible if the table is not empty.
+  - Added the required column `explain` to the `Post` table without a default value. This is not possible if the table is not empty.
+  - Changed the type of `postId` on the `PostLike` table. No cast exists, the column would be dropped and recreated, which cannot be done if there is data, since the column is required.
