prepared queries in plperl

Hello,

I've posted before a patch that enables prepared queries in plperl, and
now, after a while, as it seems working as expected, I'd like to ask if it
would be a reasonable thing to commit in into -devel? The patch against
the latest cvs is at http://www.karasik.eu.org/misc/plperl.diff .

The idea behind the patch is to make it possible to pass non-interpolated
parameters to the query:

CREATE OR REPLACE FUNCTION plus_one(INTEGER) RETURNS INTEGER AS $$ my $x = spi_prepare('SELECT $1 AS datum', 'INT4');
my$rv = spi_exec_prepared($x, $q + 1); spi_freeplan( $x); return $rv->{rows}[0]->{datum};
 
$$ LANGUAGE plperl;
