Description:
Indexes on a Selection field are never used in a `NOT IN` where clause,
as PostgreSQL doesn't have the complementary values (in DB a Selection
field is just a VarChar) to make use of an index on the field.
The ORM currently doesn't invert
`not in <selection>` -> `in <complement of selection>`.
Benchmark:
Positive impact in the project modules all around, specially for long running
projects where the proportion of "done" tasks are >90% of the
project's task. On a populated project with 10k tasks, 200 of those are
open, there were around 10x improvement on the requests linked to
rendering the kanban view of the project. More elaborate benchmarks are
available in the referenced task.
