We have already pushed the configurable lz4 toast compression code[1]. In the custom compression thread, we were already having the patch to support the compression method options[2]. But the design for the base patches was heavily modified before commit but I never rebased this patch based on the new design. Now, I have rebased this patch so that we don't lose track and we can work on this for v15. This is still a WIP patch.
For v15 I will work on improving the code and I will also work on analyzing the usage of compression method options (compression speed/ratio).
