-- Convert composite (port_id, archived_at) archived indexes to partial
|
||
|
|
-- indexes WHERE archived_at IS NULL. Every list query in the codebase that
|
||
|
|
-- hits archived_at filters on `archived_at IS NULL` (verified in
|
||
|
|
-- clients.service / interests.service / search.service / residential.service
|
||
|
|
-- / yachts.service). The composite index always carries the archived rows
|
||
|
|
-- as dead weight; the partial index is smaller, has a higher cache hit rate,
|
||
|
|
-- and lets the planner skip the index entirely when the predicate is absent.
