Hi all, I'd like to use an integer number for my primary key. I need it to be bigger than 32 bits. As far as I understand I have two options: a) use all the 64 bits of a 'bigint' b) use the 52 mantissa bits of a 'double precision' My question is, which would be faster for indexing? I assume the bigint wins here, right?
