I noticed that there is a magic number which can be replaced by CATCACHE_MAXKEYS in struct cachedesc, I checked some other struct like CatCache, CatCTup, they all use CATCACHE_MAXKEYS.
The "syscache" is the only user of the "catcache" right now. But I think they are formally separate. So I don't think the "4" in the syscache is necessarily the same as CATCACHE_MAXKEYS. For example, increasing CATCACHE_MAXKEYS, hypothetically, wouldn't by itself make the syscache support more than 4 keys.
