In principle, you can provide EXPLAIN and schema in a private email so 
we can invent a synthetic example for public discussion based on your 
problem (I wonder if it is related to one of the typical Postgres issues 
like index picking or Subplan transformation).
I already had such an experience with a company from Sydney, and it 
worked well.
