David,
it's acceptible (actually better in form of passing columns type via
bind_values) as a quick workaround for a small scripts only. Actually
as a quick workarround it's easier to downgrade DBD::Pg.
Think of numerouse DB-OO Mappers and Object Persistance tools... it
won't be easy to fix all of them. As of right now a lot of times you
get screwed if you upgrade DBD::Pg to 1.40-1.41.
