Beautifully illustrated, and in a language I readily understand as a UNIX
sys admin. Thank you, Peter!
Thank you, Bruce, Merlin, and everybody else who replied.
I love the flexibility 9.1 allows to have a default sort locale with ability
to alter locale per-query if needed. It gives us the confidence to move forward
with switching to C for sorting -- right now we only need to sort on US
English data, so this is a perfect fit. When we internationalize, 9.1
allows us to switch back to UTF8-based sorting if needed. I love it!
Thank you!
Aleksey
