Hi,

this is a follow-up to the message I posted to the thread about
additional info in GIN.

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.

Tomas
