The sqlite3_close() interface returns SQLITE_OK even if there are outstanding
...
sqlite3_stmt and sqlite3_backup objects. The connection becomes a zombie.
Resource deallocation is deferred until the last sqlite3_stmt or
sqlite3_backup object closes. This is intended to help SQLite play nicer
with garbage collectors.

Begin a series of changes designed to reduce the scope and frequency of

invalidating schemas. Design goals are that the internal schema should

that all prepared statements should be expired if the schema is invalidated.
At the same time, minimize the number of schema invalidations. This change
merely revises the sqlite3ResetInternalSchema() function to use -1 as the
wildcard for "all" rather than 0, so that we can reset the main schema
independently of all the others.
