Is this project mysql only? about casdoor

@kuchaguangjie see: https://github.com/casbin/casdoor#config

Casdoor uses XORM to connect to DB, so all DBs supported by XORM can also be used.

XORM supports a lot of DBs including PostgreSQL: https://gitea.com/xorm/xorm#drivers-support

It does support pg, but require some modification to work, since the code include some mysql specific config.

The changes I made to make it work with postgresql:

1. Create db by hand.
2. Edit conf/app.conf

• dataSourceName
  Change:

  dataSourceName = "user=postgres password=xxxxxx host=127.0.0.1 port=5432 dbname=casdoor sslmode=disable"

3. Edit object/adapter.go

• In InitAdapter()
  Change:

  adapter = NewAdapter("postgres", beego.AppConfig.String("dataSourceName"))

• In open()
  Remove:

  if err := a.createDatabase(); err != nil {
  panic(err)
  }

  Change:

  engine, err := xorm.NewEngine(a.driverName, a.dataSourceName)`

4. Edit authz/authz.go

• In InitAuthz()
  Change:

  a, err := xormadapter.NewAdapter("postgres", beego.AppConfig.String("dataSourceName"), true)

Then it will able to start.

---

BTW, I think the code could be refactored to support various db without changes. As you mentioned, it use XORM, and the dataSourceName config is for github.com/casbin/xorm-adapter/v2.
