I didn't like the space consumption. I think it's important that the
pg_control data fit in less than 512 bytes so that it doesn't cross
physical sectors on the disk. This reduces the odds of being left
with a corrupted pg_control due to partial write during power loss.
That's a second-order consideration, possibly, but I can see no
redeeming social advantage whatever to having archdir in pg_control
rather than in postgresql.conf where all the other system parameters
live. Unless you've got one, it's coming out...
