操作PG数据库

import psycopg2
import time

conn = None
try:
  conn = psycopg2.connect(database="postgres", user="postgres", host="192.168.*.*", port="5432",password='*****')
  print("Opened database successfully")
  cur = conn.cursor()
  cur.execute("select * from api")
  rows = cur.fetchall()
  result = ''
  all_field = cur.description
  for filed in all_field:
     print(filed[0])
  for row in rows:
     result += str(row[0])
     result += "\n"
  print(result)
  print("Operation done successfully")
  conn.close()
except Exception as e:
   print("ERROR ： ")
   print(e)
finally:
   print("close connction")
   conn.close()
