1) `survey_user_input.slide_partner_id`: this is a sparse column (so using
`btree_not_null` means a very small footprint). But it makes a ton of
difference when trying to delete a slide.slide.partner entry.
e.g. on a db with 500k survey inputs, the deletion of 1000
`slide.slide.partner` records goes from 40s to 100ms (400x speedup)
2) `survey_user_input_line.survey_id`: this is the inverse field of the
`survey_user_input.user_input_line_ids` O2M field, so the index is
always useful to retrieve the O2M lines. It will also marginally help
for cascading the deletion of any `survey_user_input` record from
case 1).
