<kiko> Is there a workaround for this issue?
<stub> No. We need to revert the indexes or put up with it until it is fixed upstream.
Lowering importance since it happens only using specific search terms as seen by OOPS-523A69 and OOPS-524C471. Meanwhile stub will poke psgsql developer regarding the GIN limitations.

description |
On production:
launchpad_prod=# select person.id from person where person.fti @@ ftq('-lt');
ERROR: Query requires full scan, GIN doesn't support it
Seen in OOPS-524C471
We need to try reporting this upstream, because if the index is dropped, the query works - addition of an index should not block queries from working, as the index should not be involved at all if full table scan is needed. |
Currently searching in bug comments is disabled, since it needs use to use a GIN index (for performance). When using a GIN index, searches that are too general fail, similar to this:
launchpad_prod=# select person.id from person where person.fti @@ ftq('-lt');
ERROR: Query requires full scan, GIN doesn't support it
Seen in OOPS-524C471
To workaround this we need to look at the querytree() described in Stuart's comment below, and only do the actual search if we know that we will get back a result. After we've done this, we should search in bug comments again.
