This is true that DBD::Pg doesn't support cursors, but you can write a
pl/pgsql function that returns a cursor reference and implement in this
manner:

$sth = $dbh->prepare("FETCH ALL FROM $your_ref_cursor");
while($sth->fetch){}

pl/perl was just introduced also, but I haven't looked at it enough to
know if you could use it to write the function.
