You use the module Pg:

-- 8< -- snip --
use Pg;

my $conn;
my @resultarray;
my $row;
my $col;

$conn = PG::connectdb("host=mydbserver dbname=mydatabase");

Pg::doQuery ($conn, "SELECT foo FROM bar WHERE baz=0", \@resultarray);

for $row (0..$#resultarray) {
  for $col (0..$#{$resultarray[$row]}) {
    print $resultarray[$row][$col] . "\t";
  print "\n";
-- 8< -- snap


my $result = PQexec ($conn, "....");
print $result->getvalue ($row, $col);

for more info, see 'man Pg' or 'perldoc Pg'.

   The use of COBOL cripples the mind; its teaching should, therefore, be
   regarded as a criminal offence.                  -- Edsger W. Dijkstra
