আমার পোস্টগ্রিসএসকিউএল 9.5 সার্ভারে ডেবিয়ান 8 (জেসি) -এর মাধ্যমে সরাসরি শুরু হওয়ার পরে সরাসরি বেরিয়ে যেতে থাকে service postgresql start:

active (exited)রাষ্ট্রটি নোট করুন । সার্ভারটি ডাউন আছে, যেমন আমি এটি টিসিপি বা ডোমেন সকেটের মাধ্যমে সংযোগ করতে পারছি না এবং আমি কোনও সম্পর্কিত প্রক্রিয়া খুঁজে পাচ্ছি না।
যাইহোক, যখন আমি পোস্টগ্রেএসকিউএল ম্যানুয়ালি শুরু করি তখন এটি কাজ করে:
