Hi, Just saw a fair amount of memset/memcpy in a profile, with the symbol name indicating that the compiler assumes the data is unaligned. After pondering it for a few moments, that's not too surprising: Even if the memory is allocated in the same place, the compiler has no way knowing that palloc et al always return aligned memory.
Seems like a good idea to replace palloc et al with a macro that does __builtin_assume_aligned(real_palloc(), 8) or such.
