FWIW this spring we took a stab at refactoring old patch [0] about optimizing pglz
decompression ideas into several small patches [1] [2]. We stalled when found some
regressions and work lost momentum.
If anyone is interested - we (me, Nik, Kirk) would be happy to collab. Some enthusiasm
could revive that work.
