Wouldn't that be nice!
The explosion of GUC settings is primarily a result of not enough information.
The reason there are 7 bgwriter settings, for example, is that we have no
idea what those settings should be and are hoping that people will tinker
with them and tell us. Someday when I can fully profile bgwriter, we'll just
have one setting: bgwriter_aggressive, set to a number between 0 and 9.
