Thanks for the tip. Better indexing might help, but in this case the SQL
query is clearly suboptimal, so a fix in the SQL generation is in order
anyway. In our database, a properly optimised SQL statement returns
results immediately.

The symptoms might be the same (slow queries), so the tickets might be
related, but I think this is two separate issues which will require
different solutions. One issue is about suboptimal SQL, the other issue
is about suboptimal indexes.
