Hi monks

I want to store some binary data in sql database (actually postgresql) produced by Storable::nfreeze(). How can I do it?

Test table have following structure

 Attribute |          Type          | Modifier 
-----------+------------------------+----------
 pkey      | character varying(255) | not null
 pvalue    | bytea                  | 
Index: demo_pkey

Following test code fails with error 'Unterminated quoted string at ...' for line with execute call.

#!/usr/bin/perl -w

use strict;
use Storable qw(nfreeze thaw);
use DBI;
use DBD::Pg;

# database settings
my $db_name = 'unicode';
my $db_host = 'localhost';
my $db_user = 'elric';
my $db_pass = 'test01';
my $dbh = DBI->connect("dbi:Pg:dbname=$db_name;host=$db_host;",
               "$db_user", "$db_pass");
my $test = { 'ahoj svete...',
         [ 1,
           23,
           'ttt'
         ],
       };
my $sth = $dbh->prepare("insert into demo values (?, ?)");

$sth->execute('test', nfreeze($test));

$dbh->disconnect();

exit 0;

I need to have similar functionality like MLDBM module, but for sql database. The modules Tie::RDBM, Tie::MLDBM looks buggy for me.

How can I solve this. What I'm doing wrong? or is there already preset other module for doing this?
