 Q:

Is there an inbuilt function to expand ipv6 addresses?

I'm working on a project where I need to expand IPv6 addresses. Is there an inbuilt function in Go?
What I'm currently doing is
ipv6 := "fe80:01::af0"
addr := net.ParseIP(ipv6)
fmt.Println(addr.String())

but this still prints
fe80:01::af0

What I actually need is
fe80:0001:0000:0000:0000:0000:0000:0af0

A:

There's nothing in the standard library to do this, but it's easy to write your own function. One possible approach (of many):
func FullIPv6(ip net.IP) string {
    dst := make([]byte, hex.EncodedLen(len(ip)))
    _ = hex.Encode(dst, ip)
    return string(dst[0:4]) + ":" +
        string(dst[4:8]) + ":" +
        string(dst[8:12]) + ":" +
        string(dst[12:16]) + ":" +
        string(dst[16:20]) + ":" +
        string(dst[20:24]) + ":" +
        string(dst[24:28]) + ":" +
        string(dst[28:])

 Q:

How to extract all rows from a large postgres table using python efficiently?

I have been able to extract close to 3.5 mil rows from a postgres table using python and write to a file. However the process is extremely slow and I'm sure not the most efficient.
Following is my code:
import psycopg2, time,csv
conn_string = "host='compute-1.amazonaws.com' dbname='re' user='data' password='reck' port=5433"
conn = psycopg2.connect(conn_string)
cursor = conn.cursor()
quert = '''select data from table;'''
I get the correct result. Waterline treats my column like any early, database do everything instead of me. 
 Of course I can shuffle it with early modifiers with no problems. 
 I haven't seen any complicatedness so far.
