Another argument against this is that it creates dependency among the
new GUCs. Many of the options are not compatible with each other. e.g.
postgres=# explain (timing on) select 1;
ERROR: EXPLAIN option TIMING requires ANALYZE
Would you propose we just error out in that case, or should we
silently enable the required option, or disable the conflicting
option?
