I had been under the impression that cursors don't work through DBD::Pg. I'm mistaken?

[tantarbobus]

$dbh->do(q{DECLARE imprecator CURSOR FOR SELECT * FROM tablename}) ;
my $number = 10;
my $fetch = $dbh->prepare(q{FETCH $number FROM imprecator});


##
### Fetch first $number * 10 rows.
##
while ($fetch->execute()) {
     Data::Dumper::Dumper($fetch->fetchall_arrayref());
     last if $fetch->rows() < $number;
}
