Hey Tim, Thanks for answering. I'm confused about this. You're suggesting that when I pass data either using execute(@args) or bind_param(...), that I pass blessed refs when I use array refs. And then I would code the driver to invoke some method on that class, like say serialize(), to do what I want? Seems like an irritating overhead: my @array = some_list_function(); my $scalar = some_scalar_function(); $sth->execute($scalar, bless(\@array, 'DBD::Pg::float_array')); When I could just do: $sth->execute($scalar, \@array); > For out put values then returning an array ref would be fine, though > I'd still recommend blessing it. >From the output side, getting back a blessed array ref is no different from getting an array ref, but what is the advantage to blessing it? Thanks, jas.
