The page size is only really the size of disk allocated each time. You can get many rows into a page. As you said you can't use LO's, perhaps the page size is your only chance (although I'm not sure if the text/varchar types are hardcoded to a max 4k anyhow.

Now I read something about changing the BLOCK SIZE to a higher value and recompiling the backend. But it will require more disk space to store the data, isn't it? How much disk space will I need if a chage the block size to 32K? Will it decrease performance or confiability ? Before you suggest me to use BLOBs to store theselarge strings, I'd say that I cannot change my aplication in that way. Thanks again.
