What about some C dynamically loaded function in which I could call new connection for each thread?
Past discussion here suggests that the backends are strictly single threaded. While you might be able to use multiple threads - I don't know - I expect you'd need to protect all SPI access by a lock that serialized everything anyway.

Doing it externally with a script / program that uses multiple connections might just be the way. Unfortunately that means that you don't get a single consistent snapshot - each connection will have its own, potentially different, view of the database state.

A possible use for read only transactions being able to share a snapshot came up in discussion a few weeks ago. I guess this is another one.
