SQL:

-- name: GetRecentPostsByTags :many
-- $1: TagNames
SELECT DISTINCT p.id, p.created_at, t.name AS tag_name
FROM posts p
JOIN post_tags pt ON p.id = pt.post_id
JOIN tags t ON pt.tag_id = t.id
WHERE t.name = ANY($1::text[]) AND p.created_at < $2
ORDER BY p.created_at DESC
LIMIT $3 OFFSET $4;



generated sqlc: see the annoying "Column1"
