This has been answered many times I guess: My linux filesystem is using a 4k block size. Does this mean that I can only store up to 4k in a tuple? Where exactly does that 8k limit come from? If Postgres is limited to 8k per tuple on my system right now, then it would use 2 blocks. It has been said that Postgres can use up to 32k per tuple. Is the max kb per tuple equal to the block size of the filesystem? That is, if I want 32k max tuple size, I have to put Postgres on a filesystem that is using 32k blocks (or 16k??) ? I'm confused! :) -- Robert B. Easter [EMAIL PROTECTED]
