Hi Haiyang,

Thank you for your summary.

One important thing is that we must not skip any call to ReorderBufferXidSetCatalogChanges() (direct or indirect)
duringfast-forwarding or building snapshot, because the historic snapshot only tracks txns with catalog changes, the
v6-0004seems to skip it in xact_decode(). 

Here is a related bug:
