I'm glad to see this thread. I've been mulling over this exact issue of deleted_at code leakage with a naive soft-delete implementation. My immediate thought was to use views, so its nice to see this is not yet another case of me using crack-brain ideas out of inexperience.
What's an appropriate naming convention?
Should I do it universally and put transparent views in front of all my tables so I don't have to refactor my code to point to new views whenever I do suddenly need to put in a model constraint that isn't 1:1 with my data layer? Is a transparent view a no-op in terms of perf? if it matters, this is being done in Postgres
I will probably make my constraints partial over the not-deleted records, particularly for unique constraints used for upserts. Am I about to footgun myself? Is it even necessary with the new uniqueness behavior with NULLs being implemented in postgres? Will my performance characteristics be better one way or the other in particular circumstances? It sounds like if I have a high ratio of deleted to not-deleted records a partial index becomes necessary.
