I've read and tested through the latest version of this patchset and I think
it's ready to go in. The one concern I have is that tasks can exit(1) on libpq
errors tearing down perfectly functional connections without graceful shutdown.
Longer term I think it would make sense to add similar exit handler callbacks
to the ones in pg_dump for graceful cleanup of connections. However, in order
to keep goalposts in clear view I don't think this patch need to have it, but
it would be good to consider once in.
