मैं पोस्टग्रेज 9.6 चला रहा हूं जहां मुझे डेटा के साथ एक विशेष स्कीमा निर्यात करना था।
मैंने निम्नलिखित कमांड का उपयोग किया:
pg_dump.exe -U username -d databasename -n schemaname > C:\mylocation\mydumpfilename.dmp
यदि आप बिना डेटा के केवल स्कीमा चाहते हैं, तो sइसके बजाय स्विच का उपयोग करेंn
नीचे pg_dump स्विच सूची है:
