For back branch patches,
* Wouldn't it be better to move purge logic into the function
SnapBuildPurge* function for the sake of consistency?
* Do we really need ReorderBufferInitialXactsSetCatalogChanges()?
Can't we instead have a function similar to
SnapBuildXidHasCatalogChanges() as we have for the master branch? That
will avoid calling it when the snapshot
state is SNAPBUILD_START or SNAPBUILD_BUILDING_SNAPSHOT
