Get rid of IndexIsUniqueNoCache() kluge by the simple expedient of
passing the index-is-unique flag to index build routines (duh! ...why wasn't it done this way to begin with?). Aside from eliminatingan eyesore, this should save a few milliseconds in btree index creationbecause a full scan of pg_index is not needed any more.
