Subject: Have FTS assign extremely high costs to plans that feature unusable MATCH constraints... 
X-Git-Tag: version-3.8.3~64
X-Git-Url: http://git.ipfire.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=8c7d4ddd5ad386be1aa3b90cf3b763ac78066c0b;p=thirdparty%2Fsqlite.git

Have FTS assign extremely high costs to plans that feature unusable MATCH constraints. This discourages the planner from choosing such plans, which lead to "unable to use function MATCH in the requested context" errors.
