Okay, so I took EXPLAIN ANALYZE off and made sure that timing is on "psql"
command \timing shows
Timing = on
Run the query several times..
9.1.6 runs this query an average of 354 ms
8.2.11 runs this query an average of 437 ms
So 9.1 IS FASTER
Why is EXPLAIN ANALYZE showing the reverse...of that...?
Evidently, since I fixed the database Collation ( set to a value of "C") it
has been faster but I got locked into looking at the EXPLAIN ANALYZE
results...
MMMM very curious.
Rob
