 I used 'magic number -1' to propagate not-specified information to
 autovacuum process. It might look strange because the default value is
 out of range of the reloption, but I think it has less impact to the
 codes comapred with other solutions (dynamic default values etc.).

I realized that any other solution here is going to be more complex and
thus less appropriate for backpatch.  I still don't like this very much
because it doesn't seem to offer enough flexibility to user-specified
reloptions; but any patch we come up with here is going to be applicable
to CVS HEAD.

So I'm going to apply your patch to both 8.4 and HEAD; we can always
improve it later, I guess.

Thank you for your applying.
I think the fix is ugly, too. We need to introduce cleaner solution for 8.5.

Here is a patch to fix a bug in handling default values in reloptions.
This fix should be applied to HEAD and 8.4.0.

I used 'magic number -1' to propagate not-specified information to
autovacuum process. It might look strange because the default value is
out of range of the reloption, but I think it has less impact to the
codes comapred with other solutions (dynamic default values etc.).

 To fix the bug, each field in StdRdOptions should have not-specified flag.
 If not specified, autovacuum should use current GUC settings instead of
 reloptions. Is it possible to change the default values of reloptions
 to some magic number (-1 or so) ?
