Hi,
For v17-0001-Enable-parallel-SELECT-for-INSERT-INTO-.-SELECT.patch :
+ /* Assume original queries have hasModifyingCTE set correctly */
+ if (parsetree->hasModifyingCTE)
+ hasModifyingCTE = true;
Since hasModifyingCTE is false by the time the above is run, it can be
simplified as:
hasModifyingCTE = parsetree->hasModifyingCTE
+ if (!hasSubQuery)
+ return false;
+
+ return true;
The above can be simplified as:
return hasSubQuery;
Cheers
