SQLite has accepted the cost that comes with being embedded, which is
that application-side memory-stomping bugs can destroy the database.
Postgres is not willing to make that tradeoff.  From a pure
developer's perspective, every time we got a bug report we'd have to
ask "did you observe this while running embedded?" and then demand a
repro that uses a non-embedded database.  We are not going to help
application authors debug their own bugs, especially not when we have
no visibility into what those are.

I guess they have a different set of assumptions about what that
buzzword means.
