# 有關在WSL上面的Postgredb(database)

## 起因

- 手動裝Postgredb 在windows上面一直遇到 .vbs檔案的執行問題 花了一天弄不 只好先遷就WSL
- WSL 貌似沒有`systemctl`導致 `createdb`時出現以下service沒有啟動的錯誤

  createdb: could not connect to database template1: could
  not connect to server: No such file or directory
    Is the server running locally and accepting
    connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"
