No, not really. The amount of overhead that would add --- eg, the need
for locking on what used to be single-use caches --- makes the benefit
highly questionable. Also, most people who need this find that sticking
a connection pooler in front of the database solves their problem, so
there's not that much motivation to do a ton of work inside the database
to solve it there.
