+ ** two forms, and only the specified schema is optimized in the latter two.
+ **
+ ** The details of optimizations performed by this pragma are expected
+ ** to change and improve over time. Applications should anticipate that
+ ** this pragma will perform new optimizations in future releases.
+ **
+ ** The optional argument is a bitmask of optimizations to perform:
+ **
+ ** 0x0001 Debugging mode. Do not actually perform any optimizations
+ ** but instead return one line of text for each optimization
+ ** that would have been done. Off by default.
+ **
+ ** 0x0002 Run ANALYZE on tables that might benefit. On by default.
+ ** See below for additional information.
+ **
+ ** 0x0004 (Not yet implemented) Record usage and performance
+ ** information from the current session in the
+ ** database file so that it will be available to "optimize"
+ ** pragmas run by future database connections.
+ **
+ ** 0x0008 (Not yet implemented) Create indexes that might have
+ ** been helpful to recent queries
+ **
+ ** The default MASK is and always shall be 0xfffe. 0xfffe means perform all ** of the optimizations listed above except Debug Mode, including new
+ ** optimizations that have not yet been invented. If new optimizations are
+ ** ever added that should be off by default, those off-by-default
+ ** optimizations will have bitmasks of 0x10000 or larger.
+ **
+ ** DETERMINATION OF WHEN TO RUN ANALYZE
+ **
+ ** In the current implementation, a table is analyzed if only if all of
+ ** the following are true:
+ **
+ ** (1) MASK bit 0x02 is set.
+ **
+ ** (2) The query planner used sqlite_stat1-style statistics for one or
+ ** more indexes of the table at some point during the lifetime of
+ ** the current connection.
+ **
+ ** (3) One or more indexes of the table are currently unanalyzed OR
+ ** the number of rows in the table has increased by 25 times or more
+ ** since the last time ANALYZE was run.
+ **
+ ** The rules for when tables are analyzed are likely to change in
