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. > And, does anybody know if it's possible for PostgreSQL to run a database entirely in RAM > without saving the file out to disk? > Linux has the "tmpfs" filesystem. Just put all the DB files in a tmpfs mount. Hope this helps, Jeff Davis
