Hi all, I'm new to perl. The reason I need it is that PostgreSQL RDS (Amazon) does not support python extension, but it supports perl instead. This is how it looks like in python: 
CREATE OR REPLACE FUNCTION get(uri character varying)
  RETURNS json AS
$BODY$
import urllib2
 
data = urllib2.urlopen(uri)
 
return data.read()
 
$BODY$
  LANGUAGE plpython2u VOLATILE
  COST 100;

This is how I think it should look in perl: 
CREATE OR REPLACE FUNCTION get(input_url character varying)
  RETURNS json AS
$BODY$
use warnings;

import LWP::Simple;
my $url = input_url;
my $content = get($url);
$content =~ s/ /%20/g;
return $content;
 
$BODY$
  LANGUAGE plperl VOLATILE
  COST 100;

But when I try to run my perl function it returns error: 
select get('ipinfo.io/ip');

ERROR:  Undefined subroutine &main::get called at line 6.
CONTEXT:  PL/Perl function "get"
********** Error **********

ERROR: Undefined subroutine &main::get called at line 6.
SQL state: 38000
Context: PL/Perl function "get"

Please advise.
