Rails Daily: Data Integrity and Ractor Prep
Rails maintainers landed a cluster of fixes closing gaps in Active Record's data correctness — from a PostgreSQL trigger bug that could leave foreign keys disabled database-wide, to redundant joins and stale preloader queries — while a separate multi-PR effort continues preparing core internals for Ractor support.

Good morning, it's September 2nd, and this is Rails Daily.
The clear signal today: Active Record correctness bugs, several with real production risk, dominated review activity, alongside a continued push to make Rails internals Ractor-safe.
Start with the serious one. Developer lukasedw opened three separate pull requests — 58632, 58634, and 58635 — all targeting the same bug in PostgreSQL's `disable_referential_integrity`. On older PostgreSQL versions, this method disables triggers across every table, then re-enables them afterward — but not inside an…
Two more merged fixes tighten association behavior. PR 58622 stops the preloader from treating a nil foreign key as a valid match after type conversion turned it into an empty string — previously that triggered a pointless query. And PR 58625 removes a redundant join that occurred when a `has_many through` scope…
Second theme: Ractor readiness. Gannon McGibbon's PR 58578 splits schema context attributes into an embedded object so they can vary per Ractor. In the same spirit, PR 58629 makes the `allow_browser` callback shareable across Ractors, and PR 58627 converts Action Pack settings from class-level `mattr_accessor` to…
