Hi, I use a lot of indexes on fields that typically contain lots of NULLs, so the WHERE NOT NULL partial indexing seems very useful.
However when I compare the "EXPLAIN QUERY PLAN" with a partial index vs. a normal index, SQLite won't use the index to find Max(IndexedField) if it is a partial index. Is this an optimization opportunity? I understand that other kinds of partial indexes might exclude possible Min or Max values, but a NOT NULL index would be fine for mins, maxes and most other things?
