* Precompile SQL functions to avoid overhead
* Create utility to compute accurate random_page_cost value
* Improve ability to display optimizer analysis using OPTIMIZER_DEBUG
-* Have EXPLAIN ANALYZE highlight poor optimizer estimates
+* Have EXPLAIN ANALYZE issue NOTICE messages when the estimated and
+ actual row counts differ by a specified percentage
* Consider using hash buckets to do DISTINCT, rather than sorting
This would be beneficial when there are few distinct values. This is
