No, the configure results on wrasse look pretty ordinary: checking size of void *... 8 checking size of size_t... 8 checking size of long... 8 checking alignment of short... 2 checking alignment of int... 4 checking alignment of long... 8 checking alignment of double... 8 I wondered for a moment about force_parallel_mode, but wrasse doesn't appear to be setting that, and in any case I'm pretty sure it only affects plannable statements. regards, tom lane
