+-- Fix data-integrity bug: composite FKs with bare ON DELETE SET NULL null ALL
+-- referencing columns on delete, including the NOT NULL project_id column,
+-- which raises 23502 and makes the referenced-row delete impossible.
+-- PostgreSQL 15+ supports a column-subset form: ON DELETE SET NULL (col, ...)
+-- so only the nullable column is nulled.
+
+-- ============ issues -> workspaces ============
+-- Original (0003): FOREIGN KEY (project_id, workspace_id)
+--   REFERENCES workspaces (project_id, id) MATCH SIMPLE ON DELETE SET NULL
+-- Deleting a workspace still referenced by an issue tried to null issues.project_id
+-- (NOT NULL) -> blocked workspace deletion entirely.
