When building a tuplesort during parallel GIN builds, the function incorrectly looked up the default B-Tree operator, not the function associated with the GIN opclass (through GIN_COMPARE_PROC). Fixed by using the same logic as initGinState(), and the other place in parallel GIN builds. This could cause two types of issues. First, a data type might not have a B-Tree opclass, in which case the PrepareSortSupportFromOrderingOp() fails with an ERROR. Second, a data type might have both B-Tree and GIN opclasses, defining order/equality in different ways. This could lead to logical corruption in the index. Backpatch to 18, where parallel GIN builds were introduced.
