Well, one problem there is that the connection could well have different
parameters, like search_path. Granted, probably wouldn't matter in this
case, but... Plus of course there's the cost of startup.
Something that's asked for periodically is the ability to run things
outside of a current transaction. The normal reply is to use DBLink, but
if there was backend support for that it could probably be used here.
But I suspect adding that ability would be a pretty large amount of work
