What is the correct way to specify that SQLite should perform no caching (or at least minimal caching)? PRAGMA cache_size=0 seems to have no effect - either it continues to use the default, or tries to caches everything.

Note that this does *not* control your operating systems file cache. This is SQLite's user-space cache only. If more pages than the cache allotment are required, the the cache size limit is automatically increased. D.
