Fix PostgreSQL sometimes using table scans for `event_search` (#14409) PostgreSQL may underestimate the number of distinct `room_id`s in `event_search`, which can cause it to use table scans for queries for multiple rooms. Fix this by setting `n_distinct` on the column. Resolves #14402. Signed-off-by: Sean Quah <seanq@matrix.org>
