I've applied both ginaddinfo.7.patch and gin_fast_scan.4.patch on commit b8fd1a09, but I'm observing a lot of failures like this: STATEMENT: SELECT id FROM messages WHERE body_tsvector @@ plainto_tsquery('english', 'email free') LIMIT 100 ERROR: buffer 238068 is not owned by resource owner Portal There's a GIN index on messages(body_tsvector). I haven't dug into why it fails like this.
