Never suggested *dropping* 32-bit support; that's a different question. However, if we were to receive input from 32-bit PostgreSQL users explaining why they need *high performance*, then I imagine that could affect how we feel about 32-bit optimizations. Right now, there doesn't seem to be a consensus on whether we should optimize for 32-bit or not. On the one hand, we have commit 5e1f3b9 that says: "While it adds some space on 32-bit machines, we aren't optimizing for that case anymore." On the other hand, we have the ongoing work on optimizing numeric_mul, where a patch is suggested with extra code to optimize for 32-bit. I agree, however, that the absence of any comments from such a poll would not give us any more information. /Joel
