[In case forgotten] pg_controdata and pg_waldump interfaces should also be
considered for this standardization.
Following are pg_controldata interfaces that might require change:
Latest checkpoint location:
Prior checkpoint location:
Latest checkpoint's REDO location:
Minimum recovery ending location:
Backup start location:
Backup end location:
The pg_waldump help options(and probably documentation) would also require
change:
-e, --end=RECPTR stop reading at log position RECPTR
-s, --start=RECPTR start reading at log position RECPTR
