Hi.
 
First; Is this the correct forum to ask questions about the Postgres Pro's new RUM-index?
 
If not, please point me to the right forum.
 
I think that https://github.com/postgrespro/rum/issues might be the best forum.
 
Oleg and friends; Should we use GitHub-issues as forum (one issue per question/thread?), pgsql-general or something else?
 
Andreas,
 
we are hardly working on our internal version of rum and will open it after resolving some issues. I think the best place to discuss it is -hackers.
 
Ah, as someone corrected me, we are working hard !
 
He he, I figured that was what you meant:-)
 
Ok, so basically - will RUM-index support the same indexing-properties as GIN (being able to index tsvector, BIGINT-arrays, JSONB etc.) and be able to use index for sorting on ie. timestamp, tsrank or some BIGINT-column?
 
Like my example, will it be possible to issue a query like this:
 
SELECT del.id                    , del.sent                FROM delivery del                WHERE 1 = 1
                      AND del.fts_all @@ to_tsquery('simple', 'hi:*')                      AND del.folder_id = ANY(ARRAY[2,3]::BIGINT[])
                ORDER BY  del.sent DESC LIMIT 101 OFFSET 0;
 
and have it use one RUM-index so the whole operation, including sorting, is as efficient as possible?
 
Thanks.
