Tom Lane 25ec228ef7 Track the current XID wrap limit (or more accurately, the oldest unfrozen ... XID) in checkpoint records. This eliminates the need to recompute the value from scratch during database startup, which is one of the two remaining reasons for the flatfile code to exist. It should also simplify life for hot-standby operation. To avoid bloating the checkpoint records unreasonably, I switched from tracking the oldest database by name to tracking it by OID. This turns out to save cycles in general (everywhere but the warning-generating paths, which we hardly care about) and also helps us deal with the case that the oldest database got dropped instead of being vacuumed. The prior coding might go for a long time without updating the wrap limit in that case, which is bad because it might result in a lot of useless autovacuum activity.		17 years ago
