Just my $0.02, I wouldn't take advantage of this feature as a user
without it being transparent.
I use too many of the features which would be affected by not
maintaining the state. That's one of the reasons I only use an
external JDBC pooler for my primary application, and plain ole
connections for all of my secondary services which need to just work
with temp tables, session variables, etc. I'd love it if I could use
one of those poolers (or a built in one) which just magically
increased performance for starting up connections, lowered the
overhead of idle sessions, and didn't mess with session state.
Short of that, i'll take the hit in performance and using more memory
than I should with direct connections for now.
Not sure how other users feel, but that's where i'm sitting for my use case.
