- Assert(cacheinfo[cacheId].reloid != 0); + Assert(cacheinfo[cacheId].reloid != InvalidOid); + Assert(cacheinfo[cacheId].indoid != InvalidOid); No objections about checking for the index OID given out to catch any failures at an early stage before doing an actual lookup? I guess that you've added an incorrect entry and noticed the problem only when triggering a syscache lookup for the new incorrect entry? + Assert(key[i] != InvalidAttrNumber); Yeah, same here. + Assert((cacheinfo[cacheId].nkeys > 0) && (cacheinfo[cacheId].nkeys <= 4)); Is this addition actually useful? The maximum number of lookup keys is enforced at API level with the SearchSysCache() family. Or perhaps you've been able to break this layer in a way I cannot imagine and were looking at a quick way to spot the inconsistency? -- Michael
