เกิดข้อผิดพลาดในการติดตั้ง postgres บน Windows 8

ฉันใช้แล็ปท็อป Windows 8 เป็นเซิร์ฟเวอร์ dev ของฉัน

ฉันกำลังพยายามติดตั้ง postgres บนแล็ปท็อปของฉัน แต่ฉันได้รับข้อผิดพลาดต่อไปนี้:

ปัญหาในการรันขั้นตอนหลังการติดตั้ง การติดตั้งอาจไม่สมบูรณ์อย่างถูกต้อง การเริ่มต้นคลัสเตอร์ฐานข้อมูลล้มเหลว

นี่คือวิดีโอของความพยายามของฉัน (แก้ตัวคุณภาพแย่มากฉันไม่ได้ใช้ซอฟต์แวร์จับภาพหน้าจอมาก่อน):

Solution:
- Uninstall PostgreSQL
- net user postgres /delete
- Control Panel -> User Accounts -> Configure advanced user profile properties -> delete all "Unknown User" instances that seem to be left from postgres
- compmgmt.msc -> Local Users and Groups -> Users -> New User... -> User name: postgres, Password: postgrespass -> Create
- compmgmt.msc -> Local Users and Groups -> Users -> postgres -> Member of -> Add... -> Administrators -> OK
- copy postgresql-8.4.9-1-windows.exe to C:\
- runas /user:postgres cmd.exe -> cd \ -> postgresql-8.4.9-1-windows.exe -> installed successfully without errors. Checked data folder and confirmed files created successfully.
- compmgmt.msc -> Local Users and Groups -> Users -> postgres -> Member of -> Administrators -> Remove
- compmgmt.msc -> Local Users and Groups -> Users -> postgres -> Member of -> Add... -> Power Users -> OK
- Installed HM2 -> created db successfully
- Restarted computer -> HM2 runs properly (i.e. just to check postgresql service starts automatically)
