Re: DBD::Pg, bytea type

As described in the below email, here's the patch.

Few notes:

It will always properly unquote things of bytea type when retrieved from
select. If someone has code that relies on the old behaviour, you'll need
to change that.

It will only properly enquote things when you do
$sth->bind_param(1, $xxx, DBI::SQL_BINARY);
(ie you must specify binding type to bind_param).
