I think there's plenty things that don't really make sense solving
outside of postgres:
- additional added hop / context switches due to external pooler
- temporary tables
- prepared statements
- GUCs and other session state
I think there's at least one thing that we should attempt to make
easier for external pooler:
- proxy authorization
I think in an "ideal world" there's two kinds of poolers: Dumb ones
further out from the database (for short lived processes, keeping the
total number of connections sane, etc) and then more intelligent one
closer to the database.
