pgsql: Avoid integer overflow in the loop that extracts histogram
Started by Tom Laneabout 17 years ago1 messagescomitters
Log Message:
-----------
Avoid integer overflow in the loop that extracts histogram entries from
ANALYZE's total sample. The original coding is at risk of overflow for
statistics targets exceeding about 2675; this was not a problem before
8.4 but it is now. Per bug #4793 from Dennis Noordsij.
