pub const OPTIMIZE: &str = "PRAGMA optimize;";Expand description
Re-analyse only what has gone stale (0.12.4, D-149).
SQLite tracks how much each table has changed since its last analysis and
runs ANALYZE only where it believes the statistics no longer hold. A no-op
when nothing has moved, which is what makes it safe to call on a schedule
rather than only on demand.
Bounded by ANALYSIS_LIMIT like everything else on the connection.
