Enclosed below I have a patch to allow a btree index on the int8 type.
I would like some feedback on what the hash function for the int8 hashfunctionin the ./backend/access/hash/hashfunc.c should return.Also, could someone (maybe Tomas Lockhart?) look-over the patch and makesurethe system table entries are correct? I've tried to research them asmuch as Icould, but some of them are still not clear to me.Thanks,-Ryan
