Обсуждение: pgsql: Invalidate binary search bounds consistently.
Invalidate binary search bounds consistently. _bt_check_unique() failed to invalidate binary search bounds in the event of a live conflict following commit e5adcb78. This resulted in problems after waiting for the conflicting xact to commit or abort. The subsequent call to _bt_check_unique() would restore the initial binary search bounds, rather than starting a new search. Fix by explicitly invalidating bounds when it becomes clear that there is a live conflict that insertion will have to wait to resolve. Ashutosh Sharma, with a few additional tweaks by me.
