If you look at pg_settings, there is a minimum value exposed there as 
min_val.  For some of these parameters, that number would normally be 
1.  But since we have decided that 0 is a special flag value, min_val is 
0 instead.

There are others where min_val is -1 for the same reason, where 
functionally the minimum is really 0.  Some of us would like to see 
min_val reflect the useful minimum, period, and move all these special 
case ones out of there.  That is a multi-year battle to engage in 
though, and there's little real value to the user community coming out 
of it relative to that work scope.
