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
<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 <http://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.
