Note that in this context, it's really pretty misleading to make any
blanket assertions about "Postgres does this" or "Postgres does that".
The behavior is partially determined by the client-side code, and
might well differ depending on which client library you are using,
as well as how you are using it.
For all I know, similar remarks might apply to Oracle. Do they support
more than one application-side API?
