The new v_feed-rewrite migration collided with the existing 006_user_pin_lockout (versions must be unique). Verified against a fresh Postgres: all migrations 001–010 now apply cleanly on startup. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

-- H6: replace v_feed's double LEFT JOIN + COUNT(DISTINCT) (which materializes a
|

-- likes×comments Cartesian per upload before de-duping) with correlated scalar
|
||
-- subqueries. Each count now uses its own index (idx_like_upload /
|
||
-- idx_comment_upload) and there is no GROUP BY. The output columns are
|
||
-- unchanged, so every consumer keeps working.
