Log Message: ----------- Modify AtEOXact_CatCache and AtEOXact_RelationCache to assume that the ResourceOwner mechanism already released all reference counts for the cache entries; therefore, we do not need to scan the catcache or relcache at transaction end, unless we want to do it as a debugging crosscheck. Do the crosscheck only in Assert mode. This is the same logic we had previously installed in AtEOXact_Buffers to avoid overhead with large numbers of shared buffers. I thought it'd be a good idea to do it here too, in view of Kari Lavikka's recent report showing a real-world case where AtEOXact_CatCache is taking a significant fraction of runtime.
