Hi Paul,
Please feel free to add more: I think it's that we're doing something
strange with palloc/pfree/TOAST, maybe casting, or it's something in the
PostgreSQL index AM. Do you have any success with profiling under OS X?
If so, it would be good to get at least a working profile output of both
query cases, so we can try and determine where the time is being
swallowed during the index scan.
ATB,
Mark.
