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

Jeff Davis 3758e83850 Rename cstore->columnar in SQL objects and errors. 2020-12-07 13:01:53 -08:00
Jeff Davis ad919ff220 Tests for UPDATE and error message improvement. 
UPDATEs on partitioned tables that affect only row partitions should
succeed, the rest should fail.

Also rename CStoreScan to ColumnarScan to make the error message more
relevant.
