Your use of type ScanKey in src/backend/access/brin/brin.c is a bit confusing. A
ScanKey is defined elsewhere as a pointer to ScanKeyData. When you define
an array of ScanKeys, you use pointer-to-pointer style:
+ ScanKey **keys,
+ **nullkeys;
But when you allocate space for the array, you don't treat it that way:
+ keys = palloc0(sizeof(ScanKey) * bdesc->bd_tupdesc->natts);
+ nullkeys = palloc0(sizeof(ScanKey) * bdesc->bd_tupdesc->natts);
But then again when you use nullkeys, you treat it as a two-dimensional array:
+ nullkeys[keyattno - 1][nnullkeys[keyattno - 1]] = key;
and likewise when you allocate space within keys:
+ keys[keyattno - 1] = palloc0(sizeof(ScanKey) * scan->numberOfKeys);
Could you please clarify? I have been awake a bit too long; hopefully, I am
not merely missing the obvious.
