There's a fair amount of added work to be done when updating tuples.
Will it be possible to postpone some of that to the bgwriter in a later
version? I realize that sometimes you'll still want to do the work up
front, like if it means we can stay on the same page instead of going
cold...

You're right, it would be nice.
This is what we need for faster ranking in tsearch2, since currently we should
consult heap to get positional information, which slowdowns search.
We didn't investigate the possibility to keep additional information with
index, but
The attached patch implements lo_truncate for truncating large objects to
a given length. This is required for implementing Blob.truncate in the
JDBC driver[1] and rounds out filesystem like functionality for large
objects.

I've tried repeatedly to send this patch but it doesn't seem to be getting
through. It's not in the archives or my inbox. Now that I look I realized that
none of the WIP versions of the patch that I sent arrived either. That's
fairly disappointing since I had made efforts to keep people apprised o
I think it can be interesting for other flavours of GIN usage. Is
there a way to add the number of entries of the considered indexed
item to the consistent prototype without adding too much overhead and
complexity?
We are thinking about adding extra value, but it's still only thinking.

I didn't see any improvement in terms of size of the index (14 MB for
642 738 rows in the index in both cases) or speed.
Our dictionary table contains 78367 words and its size is 3 MB.
Did I miss something?
Comparing integers is cheaper than strings. Although it hasn't significant

From a previous discussion with Teodor, it would be better to store an
int in the index instead of a text (it takes less space and is
faster). I couldn't find any example so if anyone has an advice to fix
that, it's welcome (mostly how to pack the trigram into an int instead
of a text).
