making contact via perl

Hi

I appreciate this may not be the right place to post. If it isn’t
please advise me of the correct site.

I am using windowsXP. I am trying to make contact with a psql database
called mydb that is on my computer. I can do this at the prompt, viz:

C:\Documents and Settings\Stephen>psql mydb postgres
Welcome to psql 8.0.1, the PostgreSQL interactive terminal.

Type: \copyright for distribution terms
\h for help with SQL commands
\? for help with psql commands
\g or terminate with semicolon to execute query
\q to quit

Warning: Console code page (437) differs from Windows code page (1252)
8-bit characters may not work correctly. See psql reference
page "Notes for Windows users" for details.

And I know it is there:

^
mydb=# select * from weather;
city | temp_lo | temp_hi | prcp | date
---------------+---------+---------+------+------------
San Francisco | 46 | 50 | 0.25 | 1994-11-27
Hayward | 37 | 54 | | 1994-11-29
(2 rows)

but when I try to use this perl code to make contact:

use DBI;

use DBD::PgPP

my @drivers = DBI -> available_drivers();

print "this is it @drivers";



# connecting to database
my $database='mydb';
my $username = 'postgres';
my $password = '';
my $dbh = DBI->connect("DBI:PgPP:$database",
"$username", "$password");

I get:

C:\DB>db.pl
DBI connect('mydb','postgres',...) failed: Couldn't connect to
/tmp/.s.PGSQL.543
2: at C:/Perl/site/lib/DBD/PgPP.pm line 124
at C:\DB\db.pl line 15
