One more thing:

In SetRelationNumChecks(), you should use SearchSysCacheCopy1() to get a 
modifiable copy of the tuple. Otherwise you modify the tuple in the 
relcache as a side effect. Maybe that's harmless in this case, as the 
'relhaschecksums' value in the relcache isn't used for anything, but 
let's be tidy.
