I have a subroutine I use to insert records into a postgres db. It takes as arguments the db handle, table name, and a hash containing the record to insert. I am trying to modify this to return the id of the record just inserted: 
sub insertsql {
    my ($dbh,$table,$data) = @_;
    my @qm;
    my @keys;
    my @values;
    my $i = -1;
    foreach my $k (keys %$data) {
        if (defined($data->{$k})) {
            $i++;
            $keys[$i] = $k;
            $values[$i] = $data->{$k};
            $qm[$i] = '?';
        }
    }
    my $keylist = join(",",@keys);
    my $qlist = join(",",@qm);
    my $sqlstatement = "insert into $table ($keylist) values ($qlist) 
+returning id";
    my $sth = $dbh->prepare($sqlstatement);
    my $id = $sth->execute(@values) || die "Could not execute statemen
+t: $sqlstatement $sth->errstr";
    $sth->finish();
    return $id;
}

According to postgres docs, including "returning id" in the query should make it return the last id inserted, but it doesn't. If I run this three times I get a "1" returned on each call even though when I look at the DB table I get three records with ids 1,2,3. Anybody know What I am doing wrong?
