Problem running Perl under Cygwin using Windows native 8.0

It hangs up in the connect - using DBI::pg 1.40, DBD 1.48

Code is:

my $db = "dbi:Pg:dbname=issp";
my $dbh = DBI->connect($db); #, "", "");

I also tried it with ($db, $username, $password) as well.

The problem is the call to DBI->connect() never returns.

Any assistance on this greatly appreciated.
