क्या आसान सिंटैक्स के साथ संभव है जैसे एमएस SQL ​​सर्वर 

  SELECT HOST_NAME ()

में postgresql 9.3.2? मैंने कुछ लेख पढ़ा है लेकिन कोई परिणाम नहीं!

नहीं, डिफ़ॉल्ट बिल्ड में ऐसा नहीं है। नए देशी कार्यों के साथ PostgreSQL का विस्तार करना आसान है और किसी ने पहले से ही ऐसा किया है।।

एक अतिरिक्त तरीका एक अतिरिक्त डीबी भाषा स्थापित करना होगा (PostgreSQL बहुत ही अच्छा है - आपके पास मनमानी भाषाओं का उपयोग करने का विकल्प है बजाय pl / pgsql के) और उस भाषा के अपने कार्यों का उपयोग करने के लिए कि। उदाहरण के हैं Pl / python () और pl / perl (- विश्वसनीय और अविश्वसनीय भाषाओं के बारे में चर्चा भी देखें)।
