Sorry, I thought I had -- it works like a champ. Would be nice if there
were a way to mark the signature fields as unindexed w/o having to recreate
them (not as simple as cut and paste, as the table def uses a bunch of
local definitions, but not hard), but definitely workable. And lowers the
index overhead a LOT; in my case, from 15K to <3K.
