Log Message: ----------- Fix oversight in planning for multiple indexscans driven by ScalarArrayOpExpr index quals: we were estimating the right total number of rows returned, but treating the index-access part of the cost as if a single scan were fetching that many consecutive index tuples. Actually we should treat it as a multiple indexscan, and if there are enough of 'em the Mackert-Lohman discount should kick in.
