Well, we could, but it'd also break things where we rely on
heap_inplace_update not assigning an xid. I'm not seing why that's
better than my proposal of doing this
by emitting a commit record in RecordTransactionCommmit() if nrels != 0
|| nmsgs != 0 || RelcacheInitFileInval

I don't think that follows. Inplace updates an absolute special case,
where are *not allowed* to include an xid in the tuple.
