Assuming you're using DBD::Pg and a placeholder for the bytea parameter of your
query, you must specify its type explicitly, like this:

use DBD::Pg qw(:pg_types);
[...]
$s=$dbh->prepare("INSERT INTO the_table(contents) VALUES(?)");
$s->bind_param(1, $the_data, { pg_type => DBD::Pg::PG_BYTEA });
$s->execute;

Hope this helps,
