Subject: The "PRAGMA cache_size" reads the database schema, as it has down in all prior
X-Git-Tag: version-3.8.11.1~1^2~1
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=8ea60e35c2bd3a4f7e7422772e9ab7151af4e501;p=thirdparty%2Fsqlite.git

The "PRAGMA cache_size" reads the database schema, as it has down in all prior
versions of SQLite.  This side-effect of cache_size is undocumented, but
apparently it does get used and its absence from 3.8.11 was causing problems.
