GUC instead of -X or PGXLOG : yes.
However, how is that going to work if tablespaces are introduced in 7.4. Surely
the same mechanism for tablespaces would be used for pg_xlog. As the tablespace
mechanism hasn't been determined yet, as far as I know, wouldn't it be best to
see what happens there before creating the TODO item for the log?
