There are no embedded database libraries for PostgreSQL data. Even a
well-designed embedded database library can leave your data corrupted
due to an applicaiton bug (because an embedded DB runs in the same
address space as the application, so it has no way to protect itself
from application bugs). Dangers like this, in addition to the
fundamental design differences, mean that one probably won't be
developed any time soon.

Linux has the "tmpfs" filesystem. Just put all the DB files in a tmpfs
mount.
Hope this helps,
