Back to the issue at hand. The question at the top of the thread was which of
the following behaviors we'd like by default:
(1) Compress everything within reason by default, causing slower retrieval, do
not offer substr optimization. [<= 8.3]
(2) Compress only up to 1 MB, causing faster retrieval, supporting substr
optimization. [8.4devel]
I am personally completely puzzled by option number 2. Is there even a single
use case for that?
