SQLModel emitted index=True beside primary_key=True on every id field, so 41 tables carried ix_<table>_id alongside <table>_pkey: the same single-column btree twice. 12 MB of duplicate index, and every insert maintaining both — on the hot path of a scan writing 345,152 endpoints. The planner had been using them (72,160 scans across the set) simply because they were there and equivalent; with them gone it uses the primary key, verified on subdomains: Index Scan using subdomains_pkey. The migration finds them rather than naming them, because which tables exist depends on how far an install has migrated and a name already gone must not fail an upgrade. It drops only a non-unique, single-column btree on id belonging to a table that has a primary key — no other index can match that shape. There is no downgrade: the primary key serves every lookup they served. The 33 models are corrected too, so the next hand-written migration is not comparing against a schema that would want them back. Counted honestly: 41, not the 102 an earlier pass reported — that number included the 61 primary keys themselves.
