Uh, what other kind of thread have you got in mind here?
I suppose the lack-of-cross-thread-protection issue would go away if
our objective was only to use threads for internal parallelism in each
backend instance (ie, you still have one process per connection, but
internally it would use multiple threads to process subqueries in
parallel).
Of course that gives up the hope of faster connection startup that has
always been touted as a major reason to want Postgres to be threaded...
