Hi! Sorry for delay. I was a bit busy last month. Anyway, here is my proposal for making multioffsets 64 bit. The patch set consists of three parts: 0001 - making user output of offsets 64-bit ready; 0002 - making offsets 64-bit; 0003 - provide 32 to 64 bit conversion in pg_upgarde. I'm pretty sure this is just a beginning of the conversation, so any opinions and reviews, as always, are very welcome! -- Best regards, Maxim Orlov.
