This sounds too strong to me. Session-aware load balancing is pretty
common these days. It's the default mode of PgBouncer, for example.
Not much caution required there, IMO. Or what pitfalls did you have in
mind?

..you can still get both at the same time. At least as long as you are
happy with session-aware load balancing. And who really needs finer
grained balancing?
(Note that no matter how fine-grained you balance, you are still bound
to a (single core of a) single node. That changes with distributed
querying, and things really start to get interesting there... but we are
far from that, yet).
