Nils Dijk	07d3b4fd04	fix NaN cost estimate on empty columnar tables (#4593 ) Fixing a division by zero in the cost calculations for scanning a columnar table. Due to how the columns in a columnar table are counted an empty table would result in a division by zero. Instead this patch keeps the column selection ratio on zero when this happens, resulting in an accurate cost of zero pages to scan a columnar table. fixes #4589	2021-01-27 17:32:17 +01:00
