Nope, sorry, you're being decieved.   Postgres is strictly one process, one 
query.  

You can use Bizgres MPP to achieve multithreading; it's proprietary and you 
have to pay for it.  It does work well, though.

More importantly, though, you haven't really explained why you care about 
multithreading.
