I did more checking. This time on doing cursors in perl. The key here is to go to the PostgreSQL web site and search the archives for 'cursors perl'. That yields the example (from http://archives.postgresql.org/pgsql-general/2001-01/msg01569.php:
use Pg;
my $conn = Pg::connectdb("dbname = test");
my $result = $conn->exec("begin work");
$result = $conn->exec("declare c1 cursor for select foo
from bar");
$result = $conn->exec("fetch forward 1 in c1;");
print "Hurray, I fetched a row: ",
$result->fetchrow,
$/;
$result = $conn->exec("end work;");
__SIG__
use B;
printf "You are here %08x\n", unpack "L!", unpack "P4", pack
"L!", B::svref_2object(sub{})->OUTSIDE;

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
