Subject: Enhancements to PRAGMA optimize and ANALYZE.  Add the 0x10000 flag to
X-Git-Tag: version-3.46.0~204
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=68d92c4ad3342a97ae523574cb8e09d1043970a5;p=thirdparty%2Fsqlite.git

Enhancements to PRAGMA optimize and ANALYZE.  Add the 0x10000 flag to
PRAGMA optimize.  ANALYZE now records zero-size partial indexes in the
sqlite_stat1 table.  PRAGMA optimize looks for both growth and shrinkage
in table sizes, and uses tighter bounds (10x rather than 25x) to trigger
a re-analyze.  PRAGMA optimize automatically uses are reasonable
analysis_limit to prevent excessive runtimes.
