Thread: A trivial doc patch for pgstattuple

The sgml doc mentions about HeapTupleSatisfiesNow() but currently we
have HeapTupleSatisfiesVisibility() instead.

Regards,

I think the wording is fine (and more useful) as-is.  Remember
HeapTupleSatisfiesVisibility is just a macro, and since we are calling
it with SnapshotNow, the actual decision is made by
HeapTupleSatisfiesNow.
