Some other potential issues - with only 10MB of work_mem, you might be gong to temp space on disk more than you realize.  Explain analyze might reveal that, but only if you happen to pick a query that exceeds work_mem on at least one step.
Rather than hunting blindly with EXPLAIN ANALYZE it's better to just turn log_temp_files on and see what's reported.
