The following SQL takes 4+ mins to run. I have indexes on all join fields
and I've tried rearranging the table orders but haven't had any luck. I
have done the usual vacuums analyze and even vacuum FULL just to make sure
but still the same results. The ending resultset is around 169K rows which,
if I'm reading the analyze output, is more than double. Any suggestions?
TIA
