Perhaps not multiple connections, but multiple transactions per connection, 
like Oracle supports, AFAIK. All with a big ;-) of course. I doubt it would 
be easy to implement that. The assumption one-connection-has-one-transaction 
is probably pretty deeply burried in many backend components. Has this been 
changed by the prepared-transactions stuff? I may be mistaken, which would 
be very positive news.
