I will do that (but I admit that I am not looking forward to it. When I
was young and did not make money with my computer, I liked challenges
like compiling kernels and not being able to boot the computer. Not any

WAL is on a separate disk and a separate controller, write performance:
jkr@Panoramix:/tmp$ dd if=/dev/zero of=bigfile bs=8k count=1000000
1000000+0 records in
1000000+0 records out
8192000000 bytes transferred in 166.499230 seconds (49201429 bytes/sec)
The quest continues...
